You start confined in your spaceship, but you soon overcome your borderlines and expand through hundreds of thousands of light years of space. You will be able to visit a dozen planets, and chase Desert through his journey of destruction. The path is enlighted, but you decide how to go along it.

Ternion takes place in a distant future, you are a Soldier of DTA organization.
One day, Desert, who is the capitain of a spaceship called "Ternion" and the leader of DTA, gets accidentally infected by a virus, created to provide better performance in battle.
That virus was still a prototype and they discovered causes the destruction of brain cells, and thus leads to madness.

His madness causes him to desire the destruction of every lifeful planet of the galaxy, so you, Fushiko and Yuki, start to rebel, going to any length to stop him and save the entire galaxy from a bad fate.

Ternion is a JRPG with Tactical influences.
The player will be able to move on the planets of the game with the main character and interact with the other characters.
You can encounter foes and bosses, and battles will be turn-based.
During battles the player will control a team of many characters (from 1 to 5) and the game will display the succession of turns and the everyone's HP (healt points), stamina (ability points) and HDev energy ("magic" points) bars. There will be many small mini games during the campaign.

In this game exploring plays an important role, you'll have to explore, to find the weapons and discover everything you need to defeat Desert, once and for all.
The landscapes are usually simple, but completely different from our reality, we tried to create places that looks more alien as possible, but remaining in the dictates of physics. What we are focusing more is the feeling of being "free".
Even if the maps are not as big as the classic free-roaming games, we hope to give you the sensation of the protagonist, that, after being always locked on his spaceship, is starting to discover the universe that surrouds us.
