Theory: Balduran contracted Lycanthropy.
Disclaimer: I'm going with the fact that Larian already kind of fucked up the known timeline from the previous games to do the whole Balduran-Emperor thing, especially since Ed Greenwood is saying Balduran was a human, Larian says he was an elf.
(which is HILARIOUS because Balduran didn't care much for elves per his logbook.- "Bloody elves would do well to remember that the sea belongs to no one, save the gods that guard her. I shall avoide the northerly passage just the same, if only to prevent another overzealouse boarding party. Such paranoia from the "Fair Folk..."") My headcanon for this is he went through a reincarnation spell at some point. Was a human, now an elf, does not Identify as an elf. Would fit his theme on getting transformed into other things against his will too.
Onto the actual theory:
So looking into it more, The Wandering Eye was literally found wrecked on a werewolf island. The Sword of The Emperor works against Shapechangers- like werewolves. That lines up with previous' games version of it. So that part of the lore didn't change.
He didn't go to Moonrise to seek treasure. He went looking for a cure or management of Lycanthropy. Because...WHY GO BY HIMSELF? He's used to working with a crew so he isn't exactly a lone wolf type, I'm sure *someone* would have eagerly went along with Balduran, who was famous even in his time, on an adventure. Or he could have Ansur come along again. But he didn't even *TELL* Ansur he was going!
If Ansur had known he had went there, it wouldn't have taken 10 years to drag his friend back. (Ansur apparently can just *tell* it was him, idk maybe knows Balduran/The Emperor's soul or something.)
Instead, he went alone. Maybe he was ashamed he was the same kind of being that may have killed/transformed his crew. Why he sought a place more isolated instead of a Selûnite temple in a city.
House Thorm were known Selûnites at some point. And Balduran would have known about Selûne being the goddess of good Lycanthropes because, as a sailor, would know stuff about Selûne to begin with.
And lycanthropes are NOT eaten by mindflayers for some reason. Hence instead of becoming a snack, he got tadpoled instead.
Did I get anything wrong on this or is this plausible?
