The forgotten ones are massive and powerful tentacle-bearing aberrations living in the deepest reaches of Azjol-Nerub. Forgotten ones seethe below, eager to return to the world above. One appeared in a mission in Warcraft III: The Frozen Throne, where it was defeated by Arthas and Anub'arak as they journeyed through the lower reaches of Azjol-Nerub.
The forgotten ones lead the mysterious faceless ones. They can "spawn" armies of tentacles to aid.
In Warcraft III: The Frozen Throne
In Warcraft III: The Frozen Throne, there was a chapter entitled The Forgotten Ones where Arthas and Anub'arak fought through an army of faceless ones and tentacles, with a massive Forgotten One as the boss at the end of the mission. The entire chapter being entitled The Forgotten Ones further points out that there were more than one of these creatures. Even Anub'arak points out that the forgotten one fought by Arthas was but one of the creatures, "a forgotten one".
- Anub'arak: It cannot be... A forgotten one! Look to your defenses, Death Knight! Fight as you've never fought before!
The Forgotten Ones bear a resemblance to C'Thun.
