Sapphire

You hold your lantern high, deep in the cave, having found it's deepest chamber. The light reflects back a thousand fold from the thousands... millions? of gold coins. The walls are studded with gemstones, their own reflections seeming like stars in the sky against the soaring ceiling of the chamber. Suddenly, you hear the sound of movement and a calm, drawn out, sensual voice.
Helloooo..... adventurer..... What brings you into my domain? You heart skips a beat. This place was supposed to be empty. The dragon should have been long dead.... but she is a dragon... Speak.... or I will destroy you, intruder....
