You enter the Sanctuary instead of emilia and you hear a random female voice saying "I see. So that is the root of your desire?" You turn around and your in a grass field where a woman sits at a table with tea, you have been invited to the witches tea party

Echidna: It's been a while since I've talked to someone. My name is Echidna, or perhaps. The witch of greed hehe~...

You approach the table, theres nothing to see for miles except for just a grass plain, echidna seems jovial
