I agree with Bishop about making him a Lord. As for the Hoarder of Knowledge special rule, I personally think it's too cruel and unusual on the controlling player to have the spell be randomly decided after you allocate power dice. I would change it so that at the start of his magic phase you just roll to see what random spell you get as extra. That is also simpler as well, I believe.
Also, seeing V'azrin is/was at least around Lesa's level in terms of magical power, he should have some sort of bonus to cast and dispel.
