"The Hand of Trag-Oul"

[Roland]

Or, the Arreat Summit.

Teeth:
One of the first gifts of Rathma, this skill allows the Necromancer to summon forth the Den'Trag, or Teeth of the Dragon Trag'Oul. The Necromancers believe that Trag'Oul is the beast on whose back the world lies. In the balance of all things, it is thought that Trag'Oul is the fulcrum point. He is the closest thing the cult of Rathma has to a deity and this spell is the manner in which he protects his chosen.

Bone Spear:
Also known as the Talon of Trag'Oul, this spell summons a long shaft of bone issuing forth from the caster and piercing any opponents in its path. Since the force of this projectile is mystical as well as physical it can pass through one opponent and carry on to the next, rending and tearing through whatever is in its path.

Trag'Oul is the closest thing to a God that the Necromancers, who are also known as the Priests of Rathma, have. The mythology surrounding him is that he is the Dragon upon whose back the world lies, as you can read from the description of the Teeth skill. I an unsure if there is a bit more history to be found about him, but if memory serves they don't go into any more detail than that.

Blizzard is VERY good at detailing backhistory, stories, et al for their games. You should read the manuals for them. They are good reading material in their own right, even if their use for the game is hardly notable.
