An Island Invasion
I foresee a sea shrouded in fog and gloom. Within this bit of gloomy sea sits a silent, tiny isle draped in dark mist. This isle is, in fact, completely enveloped by a Victorian, seaport town with small wharfs and narrow, cobbled streets. Along the streets are decrepit two-story buildings with overhanging balconies, all inundated with damp moss and murky shadows. There is a treasure to be found in this town - a treasure randomly placed by a protecting company of pirate ghosts whose aggression and ferociousness to protect their treasure is renowned in pirate lore.
For a captain and his crew foolhardy enough to attempt to steal the treasure, they will find that, upon landing, they will need to stand together as a firm unit in order to defeat the ghost defenses. Woe to those who fail, but, by the grace of the gods, when a majority of their unit is defeated, they will be teleported to the Raven’s Cove Jail.
Rumor has it that there are lone ghost-watchers as well as bands of roving ghosts. Further, if the captain and his crew are not stealthy enough, the whole town may be aroused. Too much talking, any traps, or any loud noises, among other things, could cause this mishap.
