The problem with a magical ship that sails itself is that no one aboard The Derleth is able to give it instructions. Perhaps that was how it came to be surrounded by three factions of ships; pirates, the British Royal Navy, and the privateers of the East India Trading company. The royal navy is interested in taking the wanted criminals among you. The pirates and East India Trading Company are after your treasure. They're not working together, exactly, they just happen to share come common goals at the moment. It's chaos on the high seas!
IT'S NEVER SIMPLE...
It's early morning and in a few hours The Derleth will be sinking. Supplies, people, bits of The Derleth, will all be washing up on the shore of a mysterious island. To be fair, it did take three small armadas to defeat The Derleth and some of the crews do have magical items designed specifically to counter those of you with higher power levels. (You're free to make up what it took to make things a fair or not so fair fight.) Your reputations preceded you which meant unfortunately, the three factions were uniquely prepared for this battle.
OOC NOTES
As usual, look for the comment headers. The last comment will be the typical "questions" header to close things out. No injury rolls, you guys get to decide what you want to happen to your characters and how hurt they get. It's up to you if your character washes up on the mysterious island or not or if they get kidnapped by one of the armadas. (I suggest characters wash up on shore so they're not cut off from RP interaction, but that's up to you and how you want to plot that out. I ain't your mama. Do what you think will be fun!)
