Someone mentioned why there aren't dwarves or centaurs in the Elven Castle. I don't know about centaurs, but as for dwarves, the answer seems obvious to me: dwarves have never been particularly friendly with elves, so that's clear. The requirements seem a bit strange.
Nothing is known about dwarves, except that there are dwarven artifacts.
It was mentioned that there are some wolves in Sylvan, but it seems to be just rumors.
