It was released in Japan on May 26, 2011, April 12, 2012 in Australia and April 13, 2012 in Europe. In January 2013, Xseed Games announced they would publish the game in North America in April 2013
The game is set on the continent of Imperia, a land once divided into 10 Kingdoms (during the course of the game there are 9 because one kingdom was taken off the Vestra (its people) by the king of Elyria). It is the year 511 of the Unified Era, which began after the War of Unification ended. A new war, the War of Independence, is occurring between Athos, Certes and Thena against Elyria and the other Kingdoms for independence from Imperia.
The game is mainly set in the Wastelands of Okanos in the Kingdom of Elyria. In these Wastelands, there is a large chasm called "The Scar", which is only stopped from growing bigger and engulfing the world by the Thirteen Towers, suspended in the middle of the valley by twelve chains connected to the surrounding cliffs. These Towers are where Aeron must collect the Master Flesh required to cure Elena of the curse.
The player assumes the role of a 22-year-old protagonist, Aeron (Voiced by: Susumu Chiba (Japanese), Ryan Philpott (English)), a taciturn former soldier of Athos. Elena (Voiced by: Mamiko Noto (Japanese), Charlotte Sanderson (English)), an 18-year-old girl who is friends with Aeron and a strong believer of the fictional Aios religion, was cursed when monsters attack the kingdom after she was chosen to sing at the Harvest Festival. Throughout the story, Aeron and Elena were assisted by a Vestra merchant named Mavda (Voiced by: Ikuko Tani (Japanese), Ann Beach (English)) — she gives Aeron the Oraclos Chain needed to lift the curse on Elena.
When developing the characters, director Toru Haga wanted players to feel related to Aeron, and he was developed to become not too outspoken or assertive. Elena was made so that players would genuinely consider wanting to save her and not consider her a burden. Mavda was based on cynical fairy-tale wizards and carries her husband around at all times. The developers decided to focus on these three characters and not expand the protagonists
