I’m feeling inspired to do some more writing today and to warm up I want to talk about the other star of the show some more, David.
When doing most of the original writing for the core story I was totally unaware of the TV tropes website, since then we have become best pals and I've been using it to help flesh out and pin down personality aspects more. I'm going to build a partial personality map for David (As the Dark Psion) using the tropes, here we go.
First and foremost we have [Cosmic Plaything](http://tvtropes.org/pmwiki/pmwiki.php/Main/CosmicPlaything), the Will of David knows no boundaries and that includes the 4th wall. David senses my (the authors, who he perceives as God/The gods) presence in the story in the form of the statistical inconsistencies that come with writing a series of events versus them naturally unfolding. Interestingly enough for me, If David ever sprang into our reality I'm probably the first and possibly only person he would kill.
Secondly but arguably just as important we have, of course, [The Determinator](http://tvtropes.org/pmwiki/pmwiki.php/Main/Determinator). Having declared Determinator (The Will of David) I want to emphasize he is NOT the kind of Determinator who throws himself blindly at his opponents (except for the end of Book 1 and beginning of book 2) and then relies on the author to make it work, on the contrary David knows the author may well sabotage his best efforts. Davids determinator status comes from a batman-like obsession.
Davids determinator expression.

That obsession and ability to always find a way leads us to [Implacable Man](http://tvtropes.org/pmwiki/pmwiki.php/Main/ImplacableMan). "Compare the [Determinator](http://tvtropes.org/pmwiki/pmwiki.php/Main/Determinator), who doesn't give up [i]despite[/i] [extreme injury](http://tvtropes.org/pmwiki/pmwiki.php/Main/GameBreakingInjury) as a result of [Heroic Spirit](http://tvtropes.org/pmwiki/pmwiki.php/Main/HeroicSpirit). Compare [The Juggernaut](http://tvtropes.org/pmwiki/pmwiki.php/Main/TheJuggernaut), who is to this trope what a tank is to a hunting dogput an obstacle in the Implacable Man's way and he'll find a way to get past it, but put an obstacle in [The Juggernaut](http://tvtropes.org/pmwiki/pmwiki.php/Main/TheJuggernaut)'s way and he'll trample over it as if it weren't even there." Depending on Davids mood and motivations he may well be the Juggernaut as well in smaller doses. A quote from David which will appear somewhere in the series is "Where there's a will, there's a way. And where there is MY WILL, there is MY WAY!" If there were a thousand doors to be opened David would have a fairly decent shot at picking the right door.
Finally bringing us to [Wobbie, Destroyer of Worlds](http://tvtropes.org/pmwiki/pmwiki.php/Main/WoobieDestroyerOfWorlds). David has heard the conversations of the gods, how they should not intervene in the affairs of men because strife lends itself to a good story (and evolution), and to intervene would ruin "the beauty" of the universe. David is repulsed by their "Prime Directive" mentality, their ability to lessen suffering yet abject refusal to do so, so David knows the answer. "If you'll not intervene to save the worlds of men, then you wont intervene to stop me from tearing down the pillars of existence. Your own stayed hand will soon wrap round your throat by my will!" David will ruin the show to spite the audience (Who he perceives as the Angels) for taking pleasure in the suffering of mankind, then trap the audience and the author in eternal nothingness.
I'm sure ill edit this one to add a few more I don't remember all the tropes that fit David off hand.
EDIT: As promised more tropes for David.
[Anti-Villain](http://tvtropes.org/pmwiki/pmwiki.php/Main/AntiVillain) David skirts the edges of this trope but honestly by the time he [becomes The Dark Psion](http://tvtropes.org/pmwiki/pmwiki.php/Main/FallenHero) he wants to be evil, [Let me be evil!](http://tvtropes.org/pmwiki/pmwiki.php/Main/ThenLetMeBeEvil) because [Being tortured makes you evil!](http://tvtropes.org/pmwiki/pmwiki.php/Main/BeingTorturedMakesYouEvil) (Instead of being picked on by other characters poor [David is picked on by the Author](http://tvtropes.org/pmwiki/pmwiki.php/Main/DrivenToMadness), prodding him ever towards the dark side.) His end goals clearly put him in the regular villain category but the [methods he uses to achieve that goal](http://tvtropes.org/pmwiki/pmwiki.php/Main/EvenEvilHasStandards), more precisely what he isn't willing to do, (mass mind control, manipulating free will, kicking puppies) brings him back around to nearly anti-villain and hopefully causes you to [cry for the devil](http://tvtropes.org/pmwiki/pmwiki.php/Main/CryForTheDevil)
I do not approach [Satan is good](http://tvtropes.org/pmwiki/pmwiki.php/Main/SatanIsGood). From Davids perspective the voice on either shoulder simply wants to manipulate him for their own purposes regardless of what the ends are and he will have nothing to do with either of them. (which makes him so difficult to mentally dominate, he is truly a loose cannon) Vecna plays the role of "the devil" as an individual being who would usurp "God" and recast the world in his image (The Illithid could also fill this role but as an organization) and David is quite content destroying him (and them) as well.
David would have a serious moral dilemma if faced with using a philosophers stone from FMA, If anything in this world is sacred to David its the will and the soul. Though Davids actions would result in the end of all things its not as if everything explodes in an Alderan-esque "cries out in pain then extinguished" , no Apocalypse, just nothing. So from David's perspective he isn't actually causing suffering as [suffering itself will cease to exist soon, retroactively.](http://tvtropes.org/pmwiki/pmwiki.php/Main/HeWhoFightsMonsters)
Driven to madness by the desire to end suffering The Dark Psion [takes no pleasure in causing mayhem and destruction](http://tvtropes.org/pmwiki/pmwiki.php/Main/TragicVillain) save for the occasional instance he is certain the victim deserves it and has likely harmed or attempted to harm him personally (the Illithid) He NEVER [Kicks the dog](http://tvtropes.org/pmwiki/pmwiki.php/Main/KickTheDog) and would likely scramble the brains of those he saw doing so should it be convenient. (this includes chickens, don't kick the chickens)
[Noble Demon](http://tvtropes.org/pmwiki/pmwiki.php/Main/NobleDemon) also applies to TDP but that's on good days, but just as often he is the [Dark Messiah](http://tvtropes.org/pmwiki/pmwiki.php/Main/DarkMessiah).
UPDATE:
OK! Here we go! This is the first rough draft, lots of terminology like "laserlike" I will edit out. This is book 1 so I want to keep the fantasy aspect high. A few of the paragraphs are abridged right now because i had the ending worked out more in detail than the beginning, ill flesh them out more. I don't know what chapter # this is yet, its somewhere between 25% and 33% through book 1.
This is the first part in the books where I'm giving hints of Davids dark side. The paralytic agent makes a comeback at the end of book 1 also when the Lich Illithid tries to paralyze David to maintain his body for use as an undead minion. David rises to his feet similarly to this chapter and blasts them both with the sun-stone.
This chapter is titled The Temple of David
Having decided that he will seek training from an ancient order of monks, David begins his ascent towards the mountain temple high in the clouds. Looking up from the base of the mountain David stood in awe at the massive stairway etched into the mountainside. After climbing for what seemed like hours David slumps against the mountain wall, exhausted from the climb and the thinning oxygen levels. Focusing his psionic powers on his bodies metabolism David overrides his bodies internal safeguards, releasing mass amounts of adrenaline and endorphins. Standing once more David resumed his ascent, running on adrenaline and willpower.
Approaching the top of the path, David staggered slowly to the gates of the mountain temple, his body reaching its limits and suffering from altitude sickness. A guard at the door looks on at David, surprised to see someone other than a monk ascending the path in a single instance. "Halt!" said the guard "What business have you at this Temple?" he asked. "I come to join your order" David said. "I seek wisdom" he panted as he sat leaned against the giant wooden doors. Surprised by Davids response the guard paused, behind him a member of the order who had overheard the conversation responds. "You must be tired from your trip, we will provide you with food and water while our elders contemplate your request."
Sleeping for the night in the guest chambers of the temple David is awoken by the elder members of the order who ask him why he wishes to join. David proceeds to explain the events that lead to him being flung into the past, his position now with knowledge of the future, and his desires to make an impact on the outcome and stop the war. Pondering Davids words for a time the elders agree to allow David to train under the monks at the temple.
Over the course of several months David is instructed in martial arts, simple physiology and medical principals, and meditative practices to calm and control ones own mind. David forms bonds with the members of the order and draws strength from their highly disciplined lives. Quickly rising through the multiple disciplines taught at the temple David becomes one of the most promising members the order has seen in decades. Nearing the skill levels of the Elders David still struggles in one area. Though David makes great strides in meditation he cannot bring himself to fully let go to enter deep meditative trances. His will fighting back from within as he tries to silence it.
David chooses to undergo an ancient ritual typically restricted to the elders themselves. Monks spend a lifetime seeking meditation to quiet the mind and as such exert great control over it. The converse of that is to induce a deep meditative trance and attempt to awaken prematurely from that trance. Elders ingest a powerful psychotropic paralytic agent to induce days long trances and use their control of their own bodies metabolisms to accelerate the healing process and awaken more quickly from an induced trance. David undergoes this ritual, and the stage is set.
Through an unlikely coincidence, the agents of the Illithid had learned of Davids location in the mountain temple, and had sought to reclaim the gauntlet and sun-stone which he had stolen from their grasp. During Davids paralysis the temple is besieged by Illithid and aberration alike in a chilling foreshadowing of the invasion to come. Though the monks are exceptionally powerful and skilled in combat, they stand little chance face to face with the Illithid and their most powerful minions. In the ritual chamber Davids mind cried out at the tipping tide of the battle outside the walls.
Seething within his own mind Davids blood boils. His comrades falling in the courtyard beyond the temple walls and beyond the reach of his powers. "DAMN IT DAMN IT DAMN IT!" David screamed in his own mind. Focusing his thoughts on his own body, David vowed he would die himself before he witnessed one more death helplessly. Releasing toxic levels of adrenaline into his bloodstream Davids body wretched on the altar, twitching and frothing at the mouth. Constricting the blood-flow to his extremities Davids blood pressure soars as the veins up his neck and along his forehead bulge and pulse with blood. His brain coursing with oxygen Davids body rolls off the altar with a dull thud on the stone floor below.
Suddenly from behind the altar Davids body rises clumsily to its feet, David controlling his paralyzed body manually through psionics like a puppet he shuffles slowly out the doorway to the courtyard beyond. Slumping down against the stone wall fascing the courtyard and witnessing the battle unfolding, saliva and froth dripping down his limp and open mouth and chin, David trained his eyes forward with laserlike precision onto the battlefield, his opponents now within line of sight and within range of his powers, Davids tortured subconscious mind runs amok set free from the inhibitions of his frontal lobe functions.
The temple, far too high to experience rain, comes under an unexpected downpour as the raging battle outside comes to a halt as both sides look on in shock as blood rains down from the heavens. Davids hatred seething and screeching within his altered mind, magnified by the new found knowledge gained at the temple, turn outwards as the horrors within Davids mind are projected into the thoughts of monk Illithid and Aberration alike. Madness sweeps the battlefield like wildfire as monk and Illithid alike babble and foam, throw themselves from the mountain top, or turn their weapons upon themselves. Directing his gaze at the pair of Illithid leading the assault David lashes out with the full extent of his powers, unhindered by restraint or remorse, instantaneously crushing the cranial cavity and liquifying the grey-matter inside. Having deduced that David is the cause of the sudden turn of tide in the battle one of the surviving Elders cries out "Thats ENOUGH David! They are routed!" Davids hateful glace turning to the Elder, and as if by instinct simultaneously hurling a boulder. David regains consciousness for a moment at the terrified sight of the Elder. Deflecting the boulder at the last moment David releases his controls of his body, his blood pressure dropping sharply, and it once again limply slumps to the ground.
