Ogre

Ogres are not known anywhere in the world of Guild Wars, despite the fact that the following items can be found:
 * Ogre-Slaying Knife
 * weapon upgrade "of Ogreslaying"
 * weapon modifiers providing special bonuses against Ogres

The GW creatures that come closest to classic Ogres, as known from fairy tales, fantasy literature, movies and RPG games would be Trolls, Ettins or Giants.
