His placement in this game is very weird. He exists pretty much ad just filling a mechanical role. The fact he is who he turns out to be... doesn't seem to actually matter to the story. I forget he's there most of the time, even. Yet he's also one of the only characters that is always going to be around, yet they don't make any narrative use of him. It's like they just thought he'd be a cool Easter egg, which honestly is what I assume their thought process was.
Similar to my takeaway as well. Using one of the most enigmatic, powerful (and possibly villainous) deities in the setting as a borderline debug npc that handles stuff that IMO should be handled by npcs (raise dead, hiring mercenaries) and debatably immersion-breaking stuff (respecs) An npc that's borderline irrelevant to the story and hardly interacts with other npcs, despite seemingly being a lich walking around in broad daylight.
Also, way too friendly/good. he should be more sinister, IMO. Even if he is trying to help us. He is not a *good* god by any means, and IIRC the writers (Ed Greenwood, etc) apparently intended him to be downright villainous, just exceedingly careful and deliberate. As in, Mystra's death and the TIme of Troubles was something he was hoping for in the first place, so having him run around 'undoing' his 'mistake' of raising the Dead Three up originally is a little off-character for him. If anything, he should probably be metaphorically nudging things with a stick to see if things spiral out of control.
As an aside, I wish his alien-looking avatar was represented in BG III. Having him appear as a bog-standard human undead is a little underwhelming.
