Though, notably, if they were so inclined they could reveal the reality of him once they finish this shadow realm, it wouldn't undo all the years he was considered a hero but might be able to fix the history from that point forward. That said, who knows how much people would trust people coming back from shadow realms, and whether desir would care about flipping the narrative like that.
I'm curious what this dude did to achieve being considered a hero, anyways. I mean it wasn't immortality unless it's extremely limited in usage to only a few people, and it probably wasn't the chimeras since... pretty fucked up. But maybe it is that.
@Rin2k Why not both? This scientist was an alternate main quest, there's still the main main quest out there.
