A long time has passed since the great destruction of the first civilization and now people once again are unlocking the mystery surrounding the dimensional gates and adventuring to unforeseen territory, seeking the magical book of infinite wisdom in Atelier Iris 3: Grand Phantasm from NIS America for the Sony PS2.

With the fast paced ACCB system, battle sequences are ordered by cards that represent the characters' action order.

There is a treasure said to have been split into eight fragments adn scattered around the world. When brought together, any wish will come true. This is the legend of the Wizard's Libram of Escalario.

Everyone has dreamed of finding it, but no one can prove it exists. Time passed, and Escalario was belived to be some legendary item in an old fairytale. But one day...

The main character, Edge, is a member of the Raider's Guild. As a Raider, his job is to venture out and explore the Alterworlds. Along with his childhood friend, Iris, he takes on quests issued by the Guild to help others in need. On a quest, they discover a piece of the Escalario.

That's when they meet their rival, who's rumored to be the strongest Raider in history. There's also an annoying raider who keeps challenging Edge, two sisters who hope to rebuild their family's lost wealth, and a mysterious man behind the scnese. It's not just Edge and Iris who want to get their hands on the Escalario!

An innovative change for Atelier Iris 3 is the introduction of a symbol encounter system, in which players no longer randomly encounter enemies, but visually confirm and engage them!
