A combination of the POTC set "Fountain of Youth" and a bunch of other pieces, the Fountain of Truth, a place where, if reached, many secrets will be revealed. As you can see in a few pictures, Jack lies dead at the base of the fountain. Turns out he mistook this place for the fabled Fountain of Youth, so uh... he didn't make it, you could say. The stone spires of this island are guarded by mermaids and the undead. There is only one way in and one way out; the waterfall. But the secrets the fountain has the power to reveal are worth the dangers and perils that surround it. In the whole world, only one map will take ye to this island of secrets. It is forever kept by Captain Teague, and no one gets to the fountain except through him.
