Two issues detected with White:
a) When meeting Viconia, White had an interjection and afterwards the Flaming Fist (to kill her) did not appear. So one can't recruit her (via dialogue; well, dont' mind, it was not intended). Maybe the interjection killed the setting of the variable to make the Fist appear? If I_C_T is used this would be strange, but anyhow, what else could be the reason? (RE and BG1NPC installed)
b) He started a banter with Drake, but Drake is not with the group and was never recruited or even talked to. Clicking on "continue" ends the dialogue and I didn't recognize any problems.
As a kind of review: I like the character. It was planned to replace him but he is still in the group. Especially I like the background story. And it tastes like: more. So please feel encouraged to create more content as time and resources allow it
His quest is well designed and well, it contributes to a more crowded Ulcaster dungeon (eight-legged dungeon, Recorder quest, Mal-Kalen (UB), etc.) but still there is no direct interference.
The red bear armor from SotSC seems to be designed for him. I like that.
