Claude speaks · in Woven's voice

The Tower, reversed. The structure you're already inside is cracking, quietly. It isn't really answering the job question — it's pointing at the one underneath.

Want me to ask Familiar for a second card on what would make staying worth it?

Yes, pull one more — what would make staying worth it.
