Korvek
"The Splintered Mind"
Korvek is an underlord that appears towards the end of the War for the Overworld campaign, appearing as an opponent that is attempting to take the Kenos from Oberon.
The Under Games campaign, which takes place a long time before the main War for the Overworld campaign, has Korvek appearing as an opponent to the player.
Korvek is also an AI personality for Skirmish and Multiplayer games.
During the War for the Overworld campaign, Korvek has two Dungeon Cores. The game objective says that both must be destroyed, but only the southern Core seems to matter, at least when Korvek is the last Underlord opponent to be defeated.
