The book itself is about how Sithis created the Aedra,but the last sentence was strange.It was in some weird language and said something about herma mora (the Skaal's name for Hermaeus Mora).
The sentence goes like this: AE herma mora Aljadoon padhome lkhan ae al.
I think "Lkhan" means "Lorkhan" and "AE" might mean "Aedra".
