Description

The Arpegia Region is back from an entirely new perspective. A land built on unity and strength, the Arpegian Archipelago reimagines Pokemon in a semi-medieval setting. By facing the Arpegia League Gauntlet, anyone has the chance to rise to the throne and rule over the land however they see fit. You play as a young girl named Faria and her Tinkatink from the desert island of Garmere. Her father, a former Gauntlet Crest Bearer, left the island years ago for reasons you aren't aware of. When you finally get the chance to leave the island and go looking for him, something happens that changes the course of your life and journey forever. Faria will be joined by a unique cast of characters as she goes on her journey to find her missing father. Kelvin is someone you've known since childhood, but the events of the game cause you to become close friends as he chases his own dreams away from Garmere Island. Mathu is a traveling bard who appears in Chapter 2; he's eccentric, outlandish, and too much almost all of the time, but he is a very powerful trainer with a lot of knowledge about myths, religion, and history.
