Mithril Horde II is an expansion by Zarista Games. It's intended for level 75 characters.

You have successfully defeated the great dragon king Bethlusaa but his spirit lives on and is now lurking in a magical tome. From his sheltering spellbook, he plots to regain power and physical form by possessing the body of Lord Yuz's cousin Yasmine. Your mission is to find the spellbook and exorcise him to the realm of the dead.
