Precursor to the Mouth of Sauron, the messenger who parleyed with the forces of Gondor at the gates of Mordor, who appeared in some notes on the draft of The Lord of the Rings (WR/256). The last two letters of this name are unclear, but Christopher Tolkien believed they might be -du (WR/267 note #32). If this reading is correct, then the name is probably a compound of morn “black” and dû “night”, as suggested by Mark Fisher (EA): The Encyclopedia of Arda: Mouth of Sauron.
