Ettin

The ettin are a race that seems to be some kind of beast resembling a cross between a giant and an ogre, living in Silverpine Forest and mountains around Gilneas and Redridge. One of these creatures came down looking for a snack, but was stopped by the worgen players. Another of these creatures was subdued by the Forsaken. Yet another of these creatures wanders the vicinity of Baradin Hold in Tol Barad and harries any Alliance or Horde forces that attempt to lay claim to the area.

Speculation
Origins of ettin remain unknown, but it's a widely speculated fact they might be related to ogres, as one is known to have ogre minions, while other ettin live in the same clan as ogres. Maybe they are ogres transformed by some sort of magic, but the exact relation remains unknown.

Another possibility, in theme with the Shattering, is that they are earth elementals affected by the Curse of Flesh.

Trivia

 * They used the gronn model as a placeholder during the World of Warcraft: Cataclysm demos.
 * The ettin also appear in Manual of Monsters Appendix Three, however the validity of this source is disputed.
 * The name Ettin is an archaic English cognate to Old Norse Jötunn (giant of Norse mythology). In the Dungeons & Dragons and Narnia universes there are Ettins with similar physique.
