Ygramul is a creature who lives in the Land of Dead Mountains. She is known as Ygramul the Many because she is made up of innumerable small steel-blue insects. She takes the form of a giant spider, using web as thick as rope to trap prey.
The Greenskins have an ancient song about Ygramul:
“Better the huntsman
Should perish in the swamps,
For in the Dead Mountains
There is a deep, deep chasm,
Where dwelleth Ygramul the Many,
The horror of horrors.”
