Look at that castle... It's a nice castle, right? You'd like to live there wouldn't you? You innocent soul...
When a magic castle pops up in the middle of private property, it spells nothing but trouble. Ponies sue over damages to property values, the plumbing infrastructure is non-existent, and the insurance rate for a disaster magnet town like Ponyville is through the roof, without even considering it being made of crystals. It's a total nightmare and it all costs money.
Twilight found herself face-to-face with such a curse. While she has managed for such a long time, she has discovered her castle is infested with the worst possible thing of all. Friends. Gathering for a summit, Twilight is about to lay down the love and tolerance down on her friends. Shenanigans ensue.
