I made the Villalfar, a civ composed of Ljosalfar who were separated from the larger part of the group that survived the Age of Ice, and became more feral than their cousins due to the harsh conditions they had to survive. They're fiercely fanatical nature worshippers (I'm about to add adept (Naturist - though I want a better word, because that also means "nudist") and mage (Guardian of Leaves) replacements, (the mage upgrading to a Druid rather than an Archmage so the player gets 6 druids). They're very tied to the Fellowship of leaves: Guardian of Nature enables their UB.
