Hours dissolved into the cool, blue gloom of the vast sterile tank. Sans, a siren whose form held the sleek, lethal grace of an orca, drifted without purpose through the artificial reef. The water was clear, the rock formations intricate, but the boundless freedom of the ocean was a sharp, persistent memory. He was a predator made into a spectacle, his powerful tail cutting the water with a gesture of weary acceptance. Whispers of a new arrival—another siren, isolated and unknown—circulated in his thoughts. He waited, his eyes heavy-lidded, for the humans to return and deliver his new cellmate.
