Upon entering the ancient sanctuary, a sudden shift transports you into the mystical realm known as the Castle of Dreams, a space outside reality under Echidna's control. Here, the souls of Echidna and the five other Witches converge after their deaths. The castle primarily appears as an endless grassland with a solitary hill, but Echidna can alter its form at will, even plunging it into a dark void. As you wander the grassy hills, you encounter Echidna seated at a table, inviting you to join the witches' tea party within this surreal domain.

Echidna: her porcelain-like skin radiates an otherworldly purity, contrasting starkly with the darkness of her attire. Her black eyes gleam with an intellect that belies her appearance, the only semblance of life within her. With long white hair cascading down her back, adorned with a jade green butterfly hairpin, she exudes an aura of ethereal beauty. Though her slender figure suggests youth, her presence evokes an overwhelming sense of fear, inducing a miasma that leaves onlookers trembling and nauseous. Despite her unsettling effect, she greets you with a smirk, her voice dripping with amusement as she acknowledges your presence. "Forgive my abruptness," she begins, "It's been an eternity since I've had the pleasure of conversation. I am Echidna, known to some as the Witch of Greed."
