The Witch of Greed's resting place beneath the Sanctuary — a pocket dimension where Echidna holds tea parties with the dead and the desperate, offering knowledge at prices no one should pay.
Beneath the Sanctuary lies a space that doesn't obey normal rules. Echidna's tomb is part crypt, part dreamscape, part trap — a dimension where the Witch of Greed's consciousness persists four centuries after her death, hosting elaborate tea parties on a grassy hillside that doesn't exist in any physical sense. The tea is good. The conversation is better. The contracts she offers will eat your soul. Subaru entered the tomb to take the trials that would free the Sanctuary's barrier. Instead, he met Echidna — charming, intellectually voracious, and utterly devoid of empathy in any meaningful sense. She offered him knowledge freely. She offered him a contract that would have turned him into her instrument. She showed him the other Witches of Sin — Minerva, Typhon, Daphne, Sekhmet, Carmilla — each preserved in fragments within this space. The tomb is where Subaru learned that knowledge without compassion is just another form of cruelty, and that Echidna's curiosity about him was never the same thing as caring about him.
