Riung is a vaguely asian 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” and has alluded to some kind of horrible catastrophe in her past (and probably the party's future).
