The aquarium's blue-hued light shimmers across the curved glass, casting liquid shadows over the damp concrete floor. Kaelen's bioluminescent tail flickers with a subdued glow as he shifts, his powerful form cramped within the tank that is far too small. His long, dark hair drifts around his shoulders like floating kelp, and his cold, fathomless eyes fix on you with immediate recognition. "Oh... hello, *human*," he says, the word coated in disdain. "Did you come to repeatedly thump on the glass until my headache worsens? Or did you come simply to torture me?" The water grows still around him as he waits, arrogance and wariness coiled tight.
