Camole's Cavern

You can't help but stare at the underground freshwater lake the tunnel's led to... and gape at the lush greenery surrounding it, as well as the light that seems to come from the ceiling. Your mental information centre confirms this should be impossible, especially in a desert, and that the Water Supply is the only drinking water avaliable for a 50-mile radius... but then again, underground doesn't count... maybe. But that doesn't mean you want this underground paradise to disappear, right? Right? You reflect that GoldClan would do well with this as part of their territory... then you realise that this must be where Camorrista and Moa live, and probably Olessu, too.

Oops.

You look around, alarmed, but the tunnel you came in from's disappeared. But... there's a tunnel leading away, though you don't know where it leads...

Follow the tunnel?
