Riung is a umichooan woman one of whose future versions has been met by Clark Dubois and Gaia Dynko.

Clark met Riung while while stoned out of his mind when captured by Victor Vituska's men. She mentioned never having met a Clark this young yet.

Gaia met Riung when her attempt to learn dreamwalking went bad and she ended shooting an apparition of Vituska on the head in the middle of a hospital, resulting on the party being captured and jailed. Riung comforted her and gave her some counsel and a plate of supernaturally delicious cookies.

Riung calls the place where she appears “one of the White Sky Towers of Umichoo”: it is a tower big enough that visitors can't see the ground or ceiling when in the middle.

Riung has alluded to some kind of horrible catastrophe in her past… and probably the party's future.

Riung is the only umichooan that the party has met yet; if her features are anything to go by, umichooans have, like anagusi, features not found in our timeline. The best description that Clark could actually give was that she “looked asian”.

Riung's cookies are able to heal headaches, menstrual symptoms, and lack of sleep.
