Hermaeus Mora

Was this book really of Daedric influence? You couldn't be sure, except...
Perhaps writing down the name of a Daedric prince will reveal some lost knowledge - even more so, the name of a Daedric prince seeped in knowledge; Hermaeus Mora.

It's a longshot, but one you're perfectly willing to entertain, even if this book so happens to be a jest by Sheogorath. You take your quill and write the Daedric Prince of Knowledge's name down.
