Death Cavalier

Death Cavalier is an undead rider knight.

Appearance
A black-armored knight which rides a red-eyed unicorn, whose body was jet black and which sported two horns on its head. One could imagine that the rider was not human. It emanated an aura of mortal danger, as radiant as the sun. Its full plate armor pulsed 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.
