My understanding is that Halsin fought against Ketheric Thorm when he served Shar, he defeated him, but Thorm unleashed the Shadow curse that has afflicted Moonrise Towers up till now.
Halsin has been studying and trying to figure out a way to undo the Shadow Curse and we now know that Thorm has switched allegiance from Shar to Myrkul (probably, we all know how 'real' the Absolute is). The Shadow curse and Thorm are linked, so undoing him might undo the curse, or vice versa.
