Enginens

Enginens refers to a fictional, advanced propulsion system featured in the *Mass Effect* video game series, developed by the fictional biotic technology company Biotic Technologies. The system is designed to enable faster-than-light (FTL) travel, allowing spacecraft to traverse vast interstellar distances in a matter of hours rather than years. Enginens operates through a process called "mass manipulation," where a ship’s mass is effectively reduced, allowing it to bypass the speed of light barrier by entering a state of "slipstream" or "warp" space.

The technology relies on a specialized fuel known as "mass relay fuel," which is often scarce and highly regulated due to its strategic importance. Enginens systems are primarily utilized by the Citadel Council, a governing body overseeing the Milky Way galaxy, and its member species. The propulsion method is depicted as highly efficient but also dangerous, as improper use can lead to catastrophic failures, such as the infamous *Normandy SR-1* incident in *Mass Effect 2*, where an Enginens malfunction resulted in the destruction of the *Normandy SR-1* and the death of its crew.

Enginens technology is central to the series' narrative, influencing political alliances, military strategies, and scientific advancements. Its development and control are often tied to broader themes of power, resource scarcity, and interstellar diplomacy. While the exact mechanics remain speculative within the game’s lore, Enginens represents a cornerstone of *Mass Effect*’s futuristic setting, enabling exploration and conflict across the galaxy.
