One was an Orc creation myth which depicted Lorkhan as a dung beetle, and Magus as a gassy fellow who farted himself into space.
The other was a Breton point of view of the Oblivion invasion with an Oblivion gate commented upon as being "a theatrical flaming [censored] hole."
I am not sure that either of these texts was put into the Imperial Library, or archived in any way. I hope they weren't lost forever because I rather enjoyed them and can no longer find them anywhere.
