Minish is a character who's been in 13Xs since it began and continues to be. Her symbol in the drawing Keys, is The Ice Crown.
A notable event that she took part in is when she went into mysterykid's place, possessed mysterykid, asked unownDB to stand on a pedestal there and performed a ritual that allowed her to steal the ability to awaken Providence right out of unownDB's body.
She then summoned and moved Providence's actual form to Autumn Twilight, placing it on a floating island. She is currently deceased, as she faded with the other pieces of Zukember upon overexerting herself killing X.
