I do understand that this is all the official lore we have. I'm not trying to just gather lore on Skyrim: TIL and UESPWiki already admirably do this. I'm trying to gather fan interpolation and extension of the Skyrim province, to serve as backstory for my game and others' fan fiction. A large part of it may be obsoleted by TES V, but I'm fine with that, because at least it gives us something to work with in the meantime.
I think I posted this in the wrong forum: it should be in Fan Fiction.
I think it will do ok here, really.
No worries. Why do you feel so?
I said that because I strongly believe that is often better to come up with a good new idea that may contradict things, rather than hold on to a bad idea.
I assume that the reluctance of people to conflict with "established" lore partially stems from the false idea that a writer should be bound by his creation for the sake of consistency. I, however, prefer to espouse the opposite school of thought, namely that a fictional work is bound by its creator. Things can only look inconsistent to us, not to the people within our fictional worlds. If one comments on inconsistencies in lore, one is really commenting on the writer, rather than the world itself. It's not changes in the fictional reality that one discerns, but just in our knowledge of that world.
