The White Destroyer (S. "Nimdagnir", Q. "Ninquenabtar") or Urk was a massive poisonous mushroom with a a I' diameter cap on a 2' stalk. A ragged, flaring reddish ring around the middle of its stalk helped distinguish the white destroyer from other giant fungi. A sac-like cup surrounded the mushroom's base.It grew in underground areas but was generally hard to find.
The fluid from the base of the fungus could be distilled into a paralytic poison that Orcs often used to coat their weapons.The only known antidotes to white destroyer poison were a tea made from slimy gorkin—and time (its effect wore off in 18 hours).
