Drell (Mass Effect)
Drell are omnivorous reptile-like humanoids with an average lifespan of 85 galactic standard years. Drell appearance is very similar to asari and humans, but their muscle tissue is slightly denser, giving them a wiry strength. They appear to have five fingers on each hand, albeit the ring and middle fingers are fused. Their skin is apparently infused with a venom mild enough to be served in drinks, and may cause mild hallucinations on “oral contact”. They also have two sets of eyelids, akin to the nictitating membrane possessed by certain animals such as reptiles. The inner lid is milky-white and closes from the left and right, while the outer lid is black and closes from top and bottom. Much like humans or asari, drell possess the ability to shed tears.
Sexual dimorphism among drell appears to be roughly analogous to humans. Females have breastlike protrusions, and their head “frills” are more pronounced than males’.
Because the drell ancestors emerged from arid, rocky deserts, the humid, ocean-covered hanar homeworld of Kahje proved tolerable only when the drell stayed inside a climate-controlled dome city. The leading cause of death for drell on Kahje is Kepral’s Syndrome, caused by cumulative long-term exposure to a humid climate. This syndrome erodes the ability of drell lungs to take in oxygen, and eventually spreads out to other organs. It is noncommunicable, and there is currently no known cure, though leading hanar scientific authorities are working on creating a genetic adaptation.
The drell possess eidetic memory, an adaptation to a world where they must remember the location of every necessary resource (vegetation, drinkable water and prey migration paths) across vast distances. The memories are so strong that an external stimulus can trigger a powerful memory recall. These recalls are so vivid and detailed that some drell may mistake it for reality. Thane Krios, for example, remembers every assassination he has ever performed and can describe them in flawless detail, and says he prefers to spend a lonely night with the perfect memory of another. This process can be involuntary.
