Bh'Yhlun

Bh’Yhlun is a structure created by the Old Ones in Ian Davey's Bh’Yhlun series of Cthulhu Mythos stories.
==Description==
Created upon the return of the Old Ones, Bh’Yhlun was formed from both the debris of the city of London and the living organic matter of its residents. It is a colossal tower which soars many miles into the sky, and across its visible surfaces can be seen the remains of the sentient creatures whose souls compose its veins and arteries, caught in an eternal agony.
The interior of Bh’Yhlun is honeycombed with passageways and cells, and patrolled by servitor Shoggoths.
==Purpose==
Bh’Yhlun is ruled by the Outer God Nyarlathotep who keeps an unknown number of humans prisoner within its walls to use as his personal playthings. It is also suggested that the tower is at least in part responsible for the changes in biosphere and atmosphere occurring since the return of the Old Ones, creating a more hospitable environment for the Earth's new masters.
