So, Enesia is my main character. As everyone knows the raging psychopathic, happy casting hands of destruction, who mutters to himself. He also seems extremely self absorbed in his research. And stole Farengar's dragonstone and book, so he couldn't defeat Enesia in learning the true nature of the dragons.
I found out why Enesia is so eternally damned in the head. His long suffering mental illness is due to a failed Lightning spell. While young Enesia was experimenting with a Lightning spell effect, he accidentally hit himself with it, sending lots of voltages through his body.
It also made his mind suffer in weird and wonderful ways. Leaving him the psychopathic he is today. Well he's more OCD than anything.
