Tomb o’the Ancients

From HammerWiki

The Tomb o’the Ancients are Dwarf burial chambers in Ekrund where ancient undead spirits are said to prowl. The entrance to the tomb is constantly guarded by Dwarf Warriors.

The Greenskins in the area know that raiding the Tomb would strike deep at the hearts of the Dwarfs, so they are attempting to plunder the burial chambers to the last bone.
