Concur. I really like Bogarus' ability to creep me out in a realistic way. Even though I haven't been played them, I enjoy encountering them in the game. I LOVE the flavor of Hinnom even though I don't play them (blood magic and cannibalism is too much for me). Definitely the most evil race. I get a huge kick out of the historical and mythological allusion behind Hinnom/Ashdod/Gath. Haven't done much with Fomoria or Tir na N'og yet (still haven't finished exploring 50% of the game).
"Hinnom eats everything!" is such a fantastic meme.
