The island floating in the middle of The Iris that orbits Terra is called Terra Ex Magus, some just call it Magus. Magus is a land dedicated to magic and is a territory of Terra. No one knows how this land got here as it just appeared in the skies one day. The land became a territory of Terra after the Terran Army invaded the land as they thought it was a group of alien invaders. To keep peace, the Magus Council decided that they would be a territory of Terra.
Over time, there were some who wanted to seize the entire world -- to not be apart of this Terra. A spellcaster named James Cooperfield made an attempt to start a war between Magus and Terra. Cooperfield, and his band of revolutionaries had prepared an army of about 200 men from all of the races of Magus and had an organized plan to try to attack Terra. This plan failed as Cooperfield and his group missed one small detail, their magic doesn't work unless within Magus. All the revolutionares were trialed for potential war crimes and were sent to Magus prisons with a life sentence.
Besides that, the people of Terra and Magus have lived together peacfully. Magus can be visited by Terrans who are asked to keep all technology, besides their KONEKTORs in Terra and the people of Magus are asked to do the same so they do not alter with the environments of each land.
