I personally like the dw fort being a tower, instead of underground. Many people are buried in towers, instead of underground. If they changed the tower to have the beds be gravestones then I think it would fit in better. They could even have vultures flying over the tower, where the flag is. In a reference to the Tower of Silence.(I also like it as a tower, because of the Pokemon Tower in Lavender town, but that's for nostalgic reasons).
But of course, that is kinda heavy stuff. Which might not sit well with the age group the game seems to be aiming for.
