Deep spire is a little different to other reality bubbles, in that it appears to rest against the base line reality in the manner of a huge boil. The exact effect of this rubbing of two realities can be seen in the corridors and dungeons beneath Black spire. Any one that ventures to deep into this hellish maze will find that the normal rules of the base line do not alway remain constant, and the deeper that one descends the more pronounced this effect becomes.
It is claimed within the pages of the Book of Eternity that it is possible to walk into this bubble with out the aid of technology or magic, simple having faith in the lich king is all that is needed. Within the bubble there is a constantly sifting maze that even M C Escher would be proud of. This maze is populated by demented ethereal undead that scream a constant prayer to the Lich king
At the very center of the Maze the Lich King him self is said to sit on his black marble throne locked in a state of meditation.
