Minor Heroes within the Warcraft Universe
All of the above appear as names for randomly generated heroes within the Warcraft III campaigns, and also for heroes used in the multiplayer of the game. As most of them have not appeared within fixed lore, their role in the wider Warcraft world can only be guessed at, if they exist as actual characters at all.

However, a number of them do have a fixed identity in the Warcraft universe, as well as acting as randomly generated heroes within Warcraft III. They are as follows:

- Araj the Summoner. A Lich who marshalled the Undead attack against Malfurion Stormrage and Tyrande Whisperwind during the events of the Frozen Throne, and went on to be a Scourge retainer in the Plaguelands.

- Morbent Fell and Ras Splinterspine. Lich Supporters of the Dreadlord Balnazzar, they were both slain by Sylvanas Windrunner.

-Morbent Fel is a level 32 necromancer in Duskwood, perhaps named after, or could be a form of the lich, Morbent Fell.

- Rage Winterchill. A Lich supporter of the Burning Legion who accompanied Archimonde in his ascent of Mount Hyjal.

- Serena Scarscale and Lady Serpentra. Naga who fought alongside Illidan Stormrage against the Night Elves on the Broken Isles and in Dalaran.

- Fordred Aran and Conjurus Rex. Archmages who fought against Arthas alongside Antonidas at the razing of Dalaran, and who were slain for their efforts. Their spirits were put to rest by Prince Kael'thas and Lady Vashj.
