The felblood elves are a group of Kael'thas Sunstrider's most loyal followers, who were rewarded by Kil'jaeden with the gift of being allowed to gorge themselves on demonic blood for days for remaining in Outland, even as many of his blood elves retreated through the Dark Portal.
Felblood Initiates remain behind at the Throne of Kil'jaeden in the Hellfire Peninsula where they feast on siphoned fel energy from Suspended Terrorguards, though many are counted amongst Kael's invading forces on the Isle of Quel'Danas. There, a felblood named Selin Fireheart can be found in the Magisters' Terrace, while a force known as the Shadowsword resides in the Sunwell Plateau — appearing to be responsible for the capturing of M'uru from the secret chamber beneath the Blood Knight headquarters.
In addition to bearing runic tattoos, they have developed various demonic features, such as unnatural skin and hair colors, horns, and what appear to be small, black-feathered wings — as well as cracks and openings in their skin, which reveal green fel energy glowing from within. Their incisors are prominent and drape idly out of their mouths during speech, giving them a vampire-like teething pattern. Unlike the Wretched, who lose most of their hair, felblood elves seem to bypass this aspect of corruption.
- Fel elf is the model name used in the game's files. It is unclear if its an actual race name or just a description. If it is the race name, that would make the felblood more of a faction term, or a nickname. Felblood has also been used to describe other demonic creatures as well, as well as the blood of terrorfiends. Like stated above, the blood elves are siphoning energy from Suspended Terrorfiends, so the fact that a terrorfiend's blood is called Felblood, and these elves are also called Felblood, makes sense.
- During the Fall of the Lich King PTR, most of the Darkfallen San'layn stationed within the Crimson Halls of Icecrown Citadel, used Felbloods' models. They were later changed to undead blood elves with Death Knight skins and unique Blood Princes models.
