Cyone, a fortified world under the protection of several asari matriarchs, has begun to supply fuel to Systems Alliance forces in the hope that an asari-human partnership might prevent the Reapers from seizing the planet. Alliance forces have since established several outposts in the system.
The humans and asari have been joined by a small detachment of turians, drawn from the private militia of a corporate conglomerate that does business with Cyone. The three species are so determined to defend Cyone that integration issues have been negligible.
The task force has already thrown back several Reaper attacks, although the commanders express concern that small Reaper forces could have slipped through despite their vigilance.
