Arantir in Heroes 5

The Hero can summon a mysterious creature upon the battlefield to fight on his side. The creature's power depends on the Hero's level. If this creature dies, the Hero will lose all his Mana points.

The lords of Heresh are a cold, grim, and fanatic group.  To climb high in their ranks requires not only talent, but also relentless dedication to the cause of their god, the spider-aspect of Asha.  Arantir has risen high indeed, and counts as one of the greatest ever to live -- or unlive -- among them.  Intense in his beliefs and dedicated to the worship of his goddess and the destruction of her demonic enemies, Arantir is a formidable leader.
