Under the sewers of a large town ancient burial chambers are discovered. If the PCs investigate they fill find that a pale white flowers grows amongst the graves, in the dark.
How do they survive without light? What is their origin? Why in a burial chamber and not just in any old cave?
Can they be sold or do they have any special quality at all? It is up to the PCs to discover.
As the players travel along the trail, they notice a bear in the woods, following thier moves. It does not make any agressive moves, but neither does it leave. As daylight fades, the players need to decide what to do. Is it a spirit guide, or gaurdian to the forest; is it a lycanthrope, or being controlled by evil spirits; or is it just a curious bear?
