I did not know such a place existed until tonight, but I'm intrigued by the name! https://en.wikipedia.org/wiki/Mischief_Reef
I dunno. This seems more realistic to me... http://www.bruzelius.info/Nautica/Ships/Clippers/Mischief(1853).html
That could be the frame for Tales of Mischief... He's a guy with the last name Mischief who goes back in time. His adventures are why Heribert Mischief is listed on Wikipedia. Heh.
