Fitzroy has finished his seafaring holiday where he did what must look suspiciously like a lot of work and not much holidaying. Now he is looking for a change and something that does not involve any mines (sea mines or otherwise). Due to inherent attraction to up and coming disasters and calamities he has learned that the nearby town's underground water facility is in a state of disrepair and the town will soon be devoid of water. Describing it as a facility might be stretching it, it is more of a series of water caves with some water infrastructure here and there.
It is now Fitzroy's challenge (as the only volunteer), (If there was anyone else I wouldn't be telling the story, now would I?) to repair the facility and escape the monsters lurking below. So now our intrepid hero must go back underground (luckily for him this is a well-lit cave system unlike his previous cave experience) for a new adventure. Rumour has it the cave also contains treasure so now is the right time to save the town and get a tiny bit wet!
