Back to the main cavern.

You return to the main cavern.

You appear to be alone. High walls of grey stone rise up into the darkness. The cavern is lit by a large glowing crystal formation in the centre, pulsing softly with a white light. Four passageways lead off this cavern. Above three of the passageways are Roman numerals: I, II, and III. The fourth is unmarked.

The crystal formation remains a deep red colour, filling you with unwanted arousal. You need to find a way out of this realm!
