The balance of Equestria has shifted far too greatly! Doom is to set upon all of life at any moment and all life will surely end! If you ask me...? This is the best time ever to get your Cutie Mark in planetary safety and escapades. What? You don't want to come? Too bad! Once you're a crusader, you're always a crusader. Every crusader has an obligation to stick it out and make sure every pony gets their cutie mark... Even in life threatening situations.
So, fighting Celestia and stopping the entirety of reality from falling apart? Yeah... That's threatening and every Crusader has to help. Why? They made swearsies.
