Merlimbis

From the Super Mario Wiki

Merlimbis, who is described by Tippi as "gentle and loving", was one of the four sages among the Tribe of Ancients. She is thought to have created the Pure Hearts, and therefore probably the Purity Heart as well. She is never directly seen, only being viewed in the form of a stained glass window in Mirror Hall; the strangely-drawn depiction of her seen in this window seems to suggest that, during her life, Merlimbis looked identical to Merluvlee the fortune teller. Indeed, both Tippi and Tiptron state that Merluvlee is a direct relative of Merlimbis, as is the similar-looking Merlee.
