Ariadne; The Architect

Ariadne didn't have much time - Arthur had gone down the street to pick up bread for her, and she had only a few minutes to set everything up.

PASIV out, set up, and then she scribbled a note: Time for your challenge. Ready? Find me, and earn your reward.

By the time Arthur returned from his errand, she would be under, waiting for him to join her in the dream she'd built.
