If you have played Diablo III you should know who Zoltun Kulle is. Anyhow, the character, and the game, have nothing to do with MLP. one of Zoltuns quotes, however, is the main reason i created this picture.
Originally Zoltun spoke about 'How imaginative' the Nephalems were when they built a secret passage behind a waterfall. ( a cliché, so yeah)
