The Death Seekers are Orcish mages; they fuel their magic on death, their own, using their blood to spread poison, tainting fields and wells.  They are rare in the Horde as their more powerful magics require their deaths to shatter enemy formations and sow terror in those who defy the Horde. Death Seekers are exclusively Orcs, as Grey Orcs have enough self-interest to avoid glorious immolation. The Death Seekers are partially genetic beings, selectively bred for specific genes, each raised to serve the Death Seekers, though learning the magic has occasionally caused unintended explosions. 

Death Seekers primarily serve as saboteurs and assassins. Poisoning wells and fields with their blood, burning food, and ammo stores. The Death Seekers know one true spell which releases the energy in their cells in a nova of kinetic energy and acid. They are used as a vanguard to shatter lines, suicidal fanatics who kill people of importance, and for destroying important infrastructure. The magic is difficult to learn, so they are used more sparingly since the destruction of the homeland. 

 The Death Seekers mostly come from a genetic stock with a familiar hierarchy. Overseen by a Greyskin who keeps the Males in line and the Females cared for.
