klasperstanze had concluded the closest truth we players know about the 3’s identities (dreeg is draellus. bysmiel is byscilla. solael is sagon). and the 3 witch gods can also possess one of their cultists for their own agendas (even the occultist’s solael aligned skill ‘possession’ support this).
as for the evil nature of most gods in grim dawn… i suspect its just the direction that crate wants to go (grimdark world). though some of them can be benevolent to lesser beings from time to time.
- dreeg is a high ranked human priest of some pantheon in korvan age. he got too close in unravelling the secret of the eldritch realm, and saw korvaak being weakened by the war of the gods. korvaak punished him to become his eldritch overseer that guards the eldritch realm from intruder. but he also bless dreeg with almost omnipotent seersights. dreeg, terrified of what korvaak plans to do with humanities for endless war against the chthonians, hatch secret plan with foreign sorcerer solael and priestess bysmiel to steal korvaak’s throne and ascend themselves to become 3 witch gods that leads humanities from the shadows for the survival of humankind (and +benefits to the 3)
2.ravager bless the cannibals of of barrowholm to protect them from ugdenbog’s dangers. but he is also the one that spreads the wendigo cannibal curse. not a benevolent being he is. he just want more cultists to get more power to strike back at mogdrogen for stealing his beastly domain while also preparing for war against the chthonians.
3.mogdrogen is more benevolent than many supreme beings of grim dawn. he wants ascetic and disarmed cultists to support his preference of wilderness over civilizations. but he also seems to be warlike if he needs to be (since he steals ravager’s domain in the past), which is the path he seems to consider in future grim dawn events post AoM, FG, & morgoneth’s beacon of the night. he considers the 3 witch gods to be capricious. and based on conversation with his avatar in ugdenbog, he seems to be preparing his followers for war after the banishment of korvaak and return of the 3 witch gods. he’s a decent supreme being imo.
