Well, Ralck, the misinterpreted the Soul Cairn. Coldharbour is described as similar to Nirn, but, you know, grim. With a ground made of "sludge". Soul Cairn didn't look like that. On the other hand, in the screenshots, you see books, tentacles, books attached to tentacles, tentacles attached to books, etcetera. It's most definitely Apocrypha.
