So, while playing Dragonborn I noticed those altars you can find in Apocrypha had some daedric text. I'm talking about this:

Yesterday I was bored, and decided to translate it. I was expecting something related to Mora, but the resulting text reads as:
THE WEAK SHALL BE WINNOWED THE TIMID SHALL BE CAST DOWN
Which is taken from Mankar's speech about Dagon's return, heard during the quest to recover the Amulet of Kings from the caves of Lake Arrius. Maybe Bethesda has decided to turn it into some kind of Daedra motto?
