Shadowfell

Shadowfell was the house of Professor Jeremy Winterdawn and his daughter Sandra Winterdawn. Following his experiments with interstitial time and the metahedron, Gabriel and Tanith built bodies from themselves in his basement while the Doctor's TARDIS materialised elsewhere in the house. Additionally, Qxeleq appeared within a cupboard and a window existed which "the unborn," creatures whose existence had been erased by time travel, tried to break through. There was a massive staircase within, and pieces of the house started to transform in relation to actions of Winderdawn. Eventually, because of Gabriel and Tanith, Shadowfell (or pieces of it) were transported to Cathedral. (PROSE: Falls the Shadow)
