"Hahahah! HahahahaHAhAhAhAhAHAHHAaH!" laughed Risa, in a non-too steady manner like it was one big cosmic joke. "The birth of the CAST was one big grand science experiment, and Risa was the result! Oh me oh my, what a wonderful terrible horrible memory that was. Long, long ago, Risa was a frail girl, with incredible powers. But Risa couldn't handle the power, it was too too much. So Risa was torn apart, and rebuilt into the very first CAST. Nowadays, those who become CAST have a choice. Most of the time."

That hanging, "Most" was a dangerous note however but she smiled. "Aether is Photons and Photons are Imagination and Magic is Magic! It's imagination and all those gooshy things inside."
