When Thaw Of The Lich Lord was first announced one of the things that got me really excited about it was the idea of the Rangifers. The Rangifers are reindeer-men or were-reindeer or something. Their origin is intentionally poorly defined to add to the sense of ancient mystery surrounding Felstad but they are basically bipedal intelligent reindeer that hate the undead.
The rangifers were needed for the fifth scenario in Thaw Of The Lich Lord where the two warbands encounter a fight between a group of rangifers and one of the Lich Lord's deadly Wraith Knights.
For the next scenario I'll be needing a Zombie Troll but I need to get my new Dungeon Crawl Classic character model done first.
