Dark Sun, The Scorched World of Athas
Unholy rituals that call forth undead hulks usually raise shambling, mindless creatures. Dread warriors, on the other hand, rise to unlife possessed of enough martial skill to serve as formidable guardians. Each dread warrior is created with an unbreakable connection to its master that makes it utterly loyal.
Safe behind a dread guardian’s heavy shield, a necromancer can hurl powers without fear or interference.

Direct combatants, the zombie knights move in to cut and smash and drag down their targets through weight of numbers.
