Read Color Castles :: Four Refugees.

Crimson. Daisy. Clover. Sparkler. All were separated from their beloved towers from the disaster that occurred. A bombing. It hit the towers and crashed them all down. Who could've possibly done it? Nobody knew. The group became scattered across the country, waiting for an answer.

Crimson currently resides in Moulathe, a small, gloomy town close by to Milwaukee. He taught at the school for a while before ultimately living in isolation, looking for his missing younger sister.

Clover is hiding at the moment in... oh dear. Wait...

I have some business to attend to.
