dreadsteed
The Dreadsteed (sometimes Felsteed) describes a small handful of variations on fiery demonic equines found in the Warcraft franchise, and can be considered a franchise-specific equivalent to a NightMare. They serve as traditional mounts to Warlocks, and broadly feature curly or bovine horns, burning eye-sockets, bony armor plates, spiny projections, white-hot hooves and fetlocks, as well as a smoldering aura of heat or cursed green fel-flame.
WARNING: It craves only fel energy. Not apples. It hates the seeds.
