Okay, I think I've settled on a character theme/background.
At this stage, he'll be a human of Chelish ancestry who was raised in a moderately wealthy family in North Point. With little physical prowess, but a sharp mind, it was almost inevitable that his family would buy him a place in the Acadamae. It was here that he was first introduced to serious gambling by another young (and rich) student, and he gravitated to games of chance - most using dice. Through this vice, he began the slow descent that so often befalls young men without the discipline to know when to quit. Eventually, through desperation, it appeared that he might almost be able to influence the dice through sheer force of will. But whether this was a product of his imagination or some innate ability was difficult to discern. Regardless, his studies at the Acadamae began to focus on spells that would enable him to predict the future to a limited excent, or learn information that might aid him, and so the path of the Diviner showed its way to him.
Unfortunately, along with the risk taking behaviour came the lure of the drugs and its sorry path. Shiver eventually became the drug of choice. And it wasn't until the drug nearly cost him his place at the Acadamae did he summon enough will to fight the addiction. Even though the fight is far from over, he is now back in control enough to know what to do. Through his spells and research, he has learned that his dealer was an employee of Gaedren's, and now he seeks an opportunity to put a stop to the trade to prevent others falling into the same trap.
Still deciding on name, whether to base the character on the Divination Domain wizard (from the Unearthed Arcana part of the SRD), the Enhanced Awareness (Ex) optional Diviner (from the SRD), or the Immediate Magic Diviner (from the PHBII). Eventual aim is to take up the Fatespinner PrC. And no familiar.
