Reflecting Dlareg

His voice echoed a little bit, though it was clearly heard by the creature. It stretched and yawned, shaking its head as it sat up. Then its eyes landed on Gerald, who was very small by comparison, and the reaction was instant.

It snarled, whole body tense and ready to attack. Gerald had no choice than to flee and shut the door. In fact, just to be sure, he should keep going in case that door wasn't enough. He'd luckily have made it so long as he reacted fast. With the thudding of heavy paws chasing him.

The beast scratched and snarled at the closed door, which thankfully could be locked from the other side - in the room where the puzzle had been. Even if Gerald left the Room of Mirrors itself, emerging back into the corridor outside, he could faintly still hear the beast. After a while, the noise stopped. Whenever he did leave the room, the mirror-door would fade.

So...What now? He had a description of the creature, and an empty room with no clear way of what to do in it. Was it another puzzle or a cruel joke?
