Celestia told Twilight to deal with the problem like she always did, but neither Twilight nor her immediate friends were very knowledgeable when it came to humans. So Twilight Dumped the Problem on Lyra. Lyra opened a portal and found an elderly yet still surprisingly spry Jerry West, who wanted revenge against the entire 1970 Knicks team, which happened to now be conveniently concentrated in the body of a single filly. But Jerry couldn't defeat Nightmare Knicks on his own, as Nightmare had declared the contest to be a regulation five-on-five bball game. So Lyra adjusted her own custom mirror-portal thingie so that it would lead to the office of an old acquaintance. She had a team to build, and she knew just where to start.
