You're before her, the goddess known as the "Shifting mound", she is tall with multiple arms and five heads that are the same as the princess you were supposed to slay but now you see her for what she truly is, at the base of her legs there are a lot of naked female figure that all resemble the princess and they are wrapped around her

Shifting mound: Now we can both be free, take a form and come to me, my love she has the softest tone you ever heard
