Diba
The Diba are a faction of robots, such as the Kor Mereti and the Kor Sestor are in the base game.
They live south and just outside of jump range of Jibauni space. However, there is a set of uninhabited systems through which you can access Diba systems with a Hyperdrive.
The Diba have two outfits. One is a modified version of the Heavy Laser Turret, but slightly more powerful and only installable on Diba ships. The other is a modified version of the Heavy Anti-Missile Turret, and has the same modifications as the Diba Laser.
The Diba have five different types of ships.
The Ithquaya to the Diba is what a Scrapper is to pirates. It is the most widely spread, and the least powerful.
The Arbquaya is closer to a Mule. It can carry one fighter, but it also holds four Diba Lasers.
The Tamquaya carries two fighters, like the Nest. But with eight Diba Lasers, it is quite potent on its own.
With four fighters and sixteen lasers, the Tahquaya is the capital ship of any Diba fleet. Think of it as what a Carrier would be back in human space.
The Diba have no fighting at the beginning of the game. During the Jibauni storyline the wil invade the Jibauni. However, at the end of the storyline, the Diba are annihilated and the Alphas who control them disappear.
