In Dragon Age: The World of Thedas Volume 2, the chapter "The Seer's Yarn: A Treasury of Tales for Children All Over" included this terrible story, "The Ptarmagin," in which a crazy mountain lord removed his own heart thinking it could somehow betray him, but for no reason, he didn't die. Instead, it merely made him incomplete and unpleasant, and he put it in a gold cask that it could, for no reason, just keep beating from.
I kid you not! All I could think was, "Did Disney approve this?"
Sorry, I just had to complain about it somewhere. But if you believe you've ever ran across a PotC ripoff, this gives you a place to post about it.
