Hey, wait, can we transplant the oak if we want to move Fireblossom later?<br/><br/>Anyway, I suggest plotting out the first corridor before we make our bigger-and-better room, so enemies will have to run a gauntlet before reaching too much of the dungeon population.  Perhaps we build it off the bottom of Fireblossom's room and let it wind around a bit before we plot out a new room?
