Death Cavalier

Death Cavalier is an undead rider knight.

Appearance
A black-armored knight which rides a red-eyed unicorn, whose body is jet black and sporting two horns on its head. One can imagine that the rider is not human. It emanates an aura of mortal danger, as radiant as the sun. Its full plate armor pulses as though it was alive.

Abilities
Similar to Death Knights, Death Cavaliers are strong creatures. Though they have the ability to properly speak unlike their cousins.

Trivia

 * Death Cavalier might be a sub-species of Death Knight.
