Story and setting. As the disclaimer at the top reads, disregard tactics advanced and a2 (main story aside). Look up the game FFT War of the Lions, and that's the setting I'm going for. (There is some mild time travel and interplanar events that occur, so I thought it'd sync up pretty well with FE: Awakening.)

Edit: btw the X is to represent the word cross, as in the game Project X Zone
