I'll start first:

Monsties that are Aptonoth are banned from Azuria due to an Aptonoth Rider getting his Aptonoth's skills during a private Rite of Channeling gone horribly wrong before his Aptonoth exploding into smithereens due to having it's Rider's skills. The same happened to the Rider. They have been declared missing ever since.
