I have it!
Jolly Roger's Island
Ok its located somewhere near the end of the Sea. (Dont worry you can gain Teleport acess from a quest
). It has a Skull shaped cave. It has a bunch of burned down buildings. Everything is all destroyed and weathered. There is a blood red sky and there is thunder. There are always a bunch of skeletons walking around. And there are 3 ship wrek's with (dead) skeletons with swords in them inside ._.. You can enter some shops. But there are just (dead) skeletons in the shops you can enter. There is a tavern with Undead skeletons in there. You can also enter Jolly Roger's cave. There are only Skeleton Bosses,Tree Stump Bosses,Wasp Bosses,Gator Bosses,Bat Bosses,Fly Trap Bosses,Scorpion Bosses and Crab Bosses. And if You Somehow make it too the end of the cave. You Will Meet. Jolly Roger. He isn't as tough as he is in an Invasion. But he is as tough as LaSchafe on Queen Anne's revenge. There is a quest for it. But im too lazy too write one down >:P .
