Slate is your average earth pony. He works hard at his town's quarry, then goes home, and goes to sleep. Ever since he started writing in a journal everything has gone wrong for him: he's having weird dreams, no one remembers who he is, and he gets fired from his job. The weirdest thing is everybody remembers someone named "Granite" and as far as they're concerned that's who Slate is supposed to be. Slate's quest for answers will take him down some frustrating roads as he tries to fix his problem.
