Fun Fact!
Before the expansion for ESO, Necrom, Hermaeus Mora took over the twitter account for ESO and revealed forbidden knowledge. They then revealed that "there is a lot of erotic literature that reaches the confines of Apocrypha, and most of it contains knowledge that I have already assimilated before, so I instead I use them as architectural pillars for my domain's chambers" So all those stacks of uninteractable books you can see in Apocrypha, both in Skyrim and in Elder Scrolls Online is canonically just a shitload of porn that he had read already.
