Since then, the drell have remained loyal to the hanar for their camaraderie and have fit comfortably into galactic civilization.
The drell ancestors emerged from dry, rocky deserts on the barren world of Rakhana. Eight centuries ago, the already-arid drell homeworld began its swift descent into lifelessness due to disastrous industrial expansion. At the time, the drell lacked interstellar flight capacity, and with their population bursting at 11 billion they faced certain doom. It was around this time that the hanar made first contact with the drell race. In the following ten years, the hanar would transport hundreds of thousands of drell to the hanar world, Kahje. The remaining billions left on Rakhana would perish on their dying planet, warring against each other for diminishing resources. The drell now thrive co-existing with the hanar and have been a part of the galactic civilization for roughly two centuries. The debt of gratitude that the drell owe the hanar is referred to as the Compact, which the drell fulfill by taking on tasks that the hanar find difficult, such as combat. Any drell may refuse to serve, but as being requested to serve is a great honor, few turn down the offer.
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. Many of their more reptilian features are concealed, however one unique characteristic is the hyoid bone in their throats, which allows them to inflate their throats and produce vocal sounds outside of the human range. They also have two sets of eyelids, like crocodiles. Drell possess the ability to shed tears.
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.
