Just thought I would join in on Dominance war and submit my character concept for the God of Time, here is the backing story for the idea:
Cronos, the original god of time, was an incorporeal being. Due to this fact, Cronos had to control inanimate objects (artifacts) using his godly powers, in order to do his bidding. Tseque (originally a demi-god) became jealous of Cronos' powers and decided to steal his artifacts to satisfy his jealousy and become more powerful. In the process he ended up defeating Cronos and using one of his 'all seeing' eyes of time to aid in Tseques ability to travel through time.
Unfortunately for Tseque, Cronos' artifacts had a curse laid upon them so that any mortal who came into possession of them would age rapidly until they met their demise. For mere humans this process would take only minutes, but Tseque survived (yay for being a demigod). Modifying some features of the artifacts, Tseque was able to merge his physical body with the artifacts to become a being of awesome power. Alas, not without some drawbacks.
Tseque must now fuel the artifacts and his body using the sands of time to prevent the aging process, converting the sands of time into a usable fuel source to keep whats left of Cronos alive (his eye, shown on the back of the concept.) Most commonly sand (silicon dioxide) is consumed using his claw (inspired by a sand worm) to prevent aging, but other carbon based 'organic' matter can also suffice such as flesh to harvest a person's life force.
Tseque now exists as a powerful god. Cronos' artifacts have given him the power to manipulate time and he exists only as a personification of time.
There are many quotes about time being inexorable......the other gods of the Dominance War will soon discover this.
