Rune is 24 years old. He's pale, with blue eyes and black hair. Rune is transgender, though this fact is kept hidden from the public. He struggles greatly with needing to hide who he really is, and can only be his true self around his personal knight and confidant—the only person who truly knows Rune inside and out.

Publicly, Rune is cold and indifferent, a result of having to hide his true self from the public. Privately, he's sweet, soft spoken, gentle, and a little self-conscious.
