M-27 Scimitar: Ariake Assault Shotgun
A Rapid-Fire Mercenary Shotgun
The M-27 Scimitar was an assault shotgun manufactured by Ariake Technologies, built around twin mass effect generators that gave it an unusually rapid rate of fire. Developed for the Eclipse, it grew popular across the mercenary bands of the Terminus.
The M-27 Scimitar Assault Shotgun was a close-quarters firearm manufactured by Ariake Technologies. Built around twin mass effect generators, it traded the heavy per-shot punch of a conventional shotgun for a far more rapid rate of fire, making it deadly in the hands of an aggressive fighter at short range. Created for the Eclipse, it spread quickly through the mercenary bands of the Terminus Systems. (Mass Effect 2; Mass Effect 3)
Design#
The Scimitar was an elite military shotgun designed for rapid fire. Its defining feature was a pair of mass effect generators, an arrangement that let it cycle far faster than a traditional shotgun and feed from a generous magazine. The result was a weapon that could pour a heavy volume of fire into a target at point-blank range, well suited to fighters who pressed in close rather than trading single shots from cover. That speed came at a price, however. Each individual round struck for less than a heavier shotgun would deliver, the weapon's accuracy was poor, and its pellets scattered widely, so its lethality depended on staying near the target and keeping up sustained fire. It was effective against kinetic shields and biotic barriers but comparatively weak against hardened armor. (Mass Effect 2; Mass Effect 3)
Origin and use#
The Scimitar was created for the Eclipse, one of the major mercenary companies operating beyond Council space. Its combination of rapid fire and ease of use made it well suited to the company's soldiers, and it did not remain exclusive for long. The weapon rapidly became popular with the Blood Pack as well, and its short-range firepower suited the close-quarters tactics both bands favored. By the time of the war against the Reapers the design remained in service, manufactured by Ariake Technologies and fielded by mercenaries and soldiers alike. (Mass Effect 2; Mass Effect 3)

Blood Pack
The Blood Pack was a brutal mercenary group built around krogan muscle and vorcha cannon fodder, founded by the exiled Battlemaster Ganar Wrang and based in the Terminus Systems. Banned from Citadel space, they took the contracts no other gang would touch, favoring overwhelming violence over discretion.

Eclipse
Eclipse was a mercenary corporation founded by the asari commando Jona Sederis, prized for advanced equipment, heavy use of biotics, and a willingness to take any contract a client could afford. It blended security work with a vast smuggling operation and counted among the three rival syndicates that ruled Omega's underworld.

Terminus Systems
The Terminus Systems were a vast, ungoverned region beyond Citadel space, home to a loose affiliation of minor species united only in refusing the Council's authority. A haven for piracy, the slave trade, and mercenary gangs, the Terminus centered on the trade hub of Omega.

Andromeda Initiative: the one-way voyage to the Heleus Cluster
The Andromeda Initiative was a privately funded, multi-species project to settle the Andromeda galaxy. Founded by Jien Garson in 2176, it sent the Nexus and its arks across dark space in 2185, and they reached the Heleus Cluster more than six centuries later to find almost nothing as promised.
Citadel Fleet: the Council's defence force and what one battle cost it
The Citadel Fleet was the Council's main space defence force, mostly turian ships led by the asari dreadnought Destiny Ascension. Sovereign's attack in 2183 caught it scattered across the relays, and Shepard decides who survives.

Vigil: the Prothean watcher of Ilos
Vigil was a Prothean virtual intelligence left to guard a hidden research facility on Ilos, built around the personality imprints of the Chief Overseer Ksad Ishan. It shut down the cryogenic pods of the people it was made to protect so that twelve might live, and fifty thousand years later it handed Commander Shepard the truth about the Citadel.
