Undershell



The Undershell is a big cave directly under L'ghorek in the Abyssal Depths. Its entrance is located in the Scalding Chasm. Inside the cavern there are three powerful ogre magi — Ur'Goz, Sku'Bu, and Neph'Lahim — maintaining a ritual that connects L'ghorek to an immense unnamed creature far below.

The cavern is also filled with Nether Fiends, which were summoned from the netherworld by the ogre magi to defend them.
