Got to say, I really hope this isn't Jergal. It seems like a serious misuse of one of the most powerful, important, and enigmatic entities in the setting to casually introduce him in the first 20 minutes of the game and then have him sit around camp, unremarked upon by companions or npcs, as essentially a gameplay convenience for if players get bodies stuck in unreachable locations and need to resurrect. Ideally npc priests would do that like in BG I+II, but afaik Larian just doesn't trust players to not kill them and leave themselves in a situation where they can't resurrect?
Apparently it is already known or at least heavily speculated that Withers is indeed Jergal, as the 3D model for Withers was named Jergal on the artist's showcase page.

And also this dialogue in which a Cleric can detect divine energy within him.
Reddit postBut yes, so far he just seems to be a glorified revival bot with some interesting backstory and plenty of sass ^^
