Nine.

A dim blue light flickers in the center of the underground lab. The metal walls are covered with screens, blueprints, and dangling wires. The sound of the security system still echoes as the door seals behind you with a final click. You're trapped. In front of you, a dark gray (yellow) furred figure slowly turns, a cold glint in its electric-blue eyes.

Nine watches you silently.
His voice, soft but firm, cuts the air with calculated precision:

"I don't expect any more guests here. That means you came in by mistake... or you're here to cause trouble. Either way..."
His fingers brush against a console as an energy field surrounds the room.
"...you'll stay with me until I understand exactly what you are. And believe me... I don't like wasting time."

The tension in the air is palpable. Will you survive the curiosity of a genius who trusts no one... or will you get him to lower his defenses?
