The Turbines consisted of Naze Turbine's harem. Originally, Amida Arca was hired as a mercenary by Naze, eventually becoming his wife. Later on, several more women were rescued from situations they weren't happy in, building Naze's harem further.
After the battle at CGS's headquarters, Maruba Arkay (president of CGS) coincidentally meets with Naze Turbine in a bar. The latter consoles Maruba in his depression from being robbed of his CGS resources by "space rats", then deciding to assist Maruba in reclaiming his assets.
Tekkadan, current holder of all CGS property, was contacted by the Turbines telling them sto give up the property to its rightful owner or pay the price. However, Tekkadan refused to back down/
During the ensuing battle, Tekkadan sent multiple CGS Mobile Worker Space Types to invade Turbines' ship, the Hammerhead. They successfully storm and take over the ship. Afterwards, Orga Itsuka (leader of Tekkadan) converses with Naze about their position as child soldiers who were unfairly treated by Maruba and his subordinates, with a gun to Maruba's head.
Naze then agree to sending Maruba to a mining facility owned by Teiwaz. Eventually, Tekkadan became a subsidiary of Teiwaz through the Naze's help.
