The Sunken Sin
An abandoned ship destined to sail till the end of times.
Unfortunately, crashed down in the gulf of Eviltown, beyond repair.
Eviltown residents made it into a PVP arena with 2 layers and openable water drainage valves.
Legend goes around that the sins of the sailors who abandoned it carried on with the cursed waters it sailed through, and that the ship might have mystical power to cleanse karma and sins, of course for an offering.
