Pillars of Eternity's writing had exactly two interesting elements:
- Avellone's character work;
- and the twist at the end about their gods being man-made.
That's it. I barely recall anything other than the wind stealing your soul, there being a fort, a grey city and a watermill, nor anything about characters beyond physical characteristics, like the feathered woman or the dwarf lass with a pet wolf. I think there was also a not-orc companion with sharp teeth, I see his portrait around these forums sometimes? That's two companions whose most memorable quality is appearing next to Codex shitposts.
Anyway, I remember Durance for his character, a broken and abrasive man, misshapen by his own failures and resentment into a fount of twisted wisdom without dignity. I don't recall anything about Pellagina beyond the "riveting" online debate about whether or not she had a cloaca.
P.S. No, actually, I guess I vaguely remember Eder's personality too, I remember him being dull. They were going for the relatable everyman (which I appreciate and RPGs need more of) but they overshot. For a counterexample, see Safiya in MotB - setting her backstory aside, she's the adult in the room (even as MotB's cast are more mature and composed in general), she's rational and reasonable, but she makes an impression to that end. Eder doesn't, he's just kinda "there."
