Carock

I began with Carock. Carock is a magician and an illusionist who can only be beaten by his own magic. In Skyrim, he would likely have a high capacity for Illusion and Destruction but not have any particular protection against these schools of magic. I picture him as pale, gaunt, and skeletal with sunken eyes. However, the original game shows only a tall figure covered by a red robe (a bright red version of the Archmage's Robes would maybe be ideal).

In Skyrim, Carock was sentenced to execution for murder (after trying to perfect an esoteric Destruction spell on a large farming family). Prior to his arrest, Carock was unknown. He prefers seclusion from people and society and shows his face only to practice his dark arts as he pursues deeper, grander forms of power. After escaping arrest, he again disappeared, maintaining a low profile in the basement of a cabin hidden in the woods west of Riverwood. Carock quickly overpowered the cabin's original owner, a reclusive low-level witch, and then dumped her in the river.

Carock was drawn to a dark crypt in the mountains looming above him, where he renewed his search for great power and hidden knowledge. He has not been seen by living eyes for months.
