Diagna or Orichalc God of the Sideways Blade was said to be the avatar of HoonDing, coming from Yokuda during an event known as the Twenty Seven Snake Folk Slaughter. He brought orichalc weapons to the Yokudans which aided them in defeating the Lefthanded Elves.
In Tamriel, he had a number of followers who called themselves the Order of Diagna. This order was responsible for defeating the Orcs during the Siege of Orsinium. Eventually he became unrecognized, known only as a local power spirit of the Dragontail Mountains.
