Seth Sigler wanted a normal life.
Lyra Heartstrings wanted to try to impress Twilight and the Gang with the Rainbow Bridge Spell.
Equestria at large wanted a break after Tirek happened.
Sunset Shimmer wanted to get away from the drama at CHS.
FIMfiction wanted a unique story.
None of that actually happens at all.
Other tag for characters that will play a role but I couldn't get tagged into the story due to reasons.
