Currently extinct creatures that were introduced with the Good/Evil system for Siege Perilous. For a short while these animals also spawned on regular shards.
Good aligned, very strong horses that seem to glow. They will attack all Evil beings and monsters on sight. Their preferred method of attack is magic, their fireballs can do 30 damage per hit. Stat and skillwise they fall in the same category as the Nightmare. Killing a Silver Steed may increase your Fame but will lower your Karma, depending on what levels you currently are ofcourse.
