Drek'thar's Spellbook

Drek'thar's Spellbook is an old and seemingly simple spellbook, filled with pages stolen from Kirin Tor mages that were slain in battle. Drek'thar gave it away to Rexxar as a reward for collecting three massive thunder lizard eggs for his research efforts to study thunder lizards' ecology.

Background
This ragged tome is covered by a sheath of carved wood kept sealed by interlocking teeth. Originally the property of the orcish sorcerer Drek'thar, it reeks of powerful magic.
