Frontier isle

The Frontier isle is the large island where Andre and Denvor,still accompanianed by Lyra, go to train and prepare for their trip to the Isshu region. Aside from having all the normal facilities of a city, such as streets, buildings and a harbor, the Frontier isle holds different Colosseums, each with their different rules and a leader. In this, it is highly similar to the Battle Frontier in Johto, Hoenn and Sinnoh.
