A child of time, Danuin represented Day in the book of Lost Tales. He had two brothers named Ranuin and Fanuin, and their father was Aluin.They appeared in the guises of old men, similar to the Istari, and Danuin was considered the first son being Day, and followed by Month and Year, and appeared as a small or short man. Danuin also had short hair and a small beard.They may have become Maiar of Vaire, the Weaver of Time or they may have returned to Aluin in the Timeless Halls, which is more plausible.
MERPS/ICE[]
Not sure if ICE/MERP did anything with these individuals or if they made them into Maia--but if they did so, then Danuin, Fanuin, and Ranuin would not only be Maia, but they would be Maiarindi as well. It is unknown if MERP actually used these characters, but given that they are Ainur who exist in Arda--GM's may use them in their campaigns if they want to. Obviously GMs will have to come up with stats and levels for them using the ICE character law.
