the gods are the worst part of forgotten realms, in my opinion.
none of it makes much sense. they're all these supposedly powerful beings that are about as smart as whoever happens to be writing them at the moment, which means that they're about as dumb as the average human sometimes. And their actions and powers and limitations and whatnot: it's all handwaving.
it's one of the problems you get when you have so many people involved in a creation over time. there are the occasional visionaries who bring gold to the table, and then there's everyone else, alas.
