Mordin Solus

Mordin Solus  is a salarian geneticist, professor, and a former operative of the Special Tasks Group (STG), where he performed reconnaissance and participated in the modification of the genophage. In 2185, he is recruited by Commander Shepard to assist in a high-risk mission against the Collectors. Mordin has a moral character best described as consequentialistic, believing the ends justify the means, though he dislikes taking life without good cause. His actions are often guided by an impersonal logic, refusing to let his conscience, personal, and emotional connections cloud his judgment of what he believes is truly best in the big picture. Though he is affable, quick-talking and friendly, Mordin bears physical scars of his time in the STG and is still handling the consequences of his past.

History
Born sometime in the 2150s, Mordin Solus is an expert geneticist, doctor, scientist and a former member of the salarian Special Tasks Group. His last mission in the STG before retiring involved the study of the krogan genophage. For this task, Mordin personally led a science team of geneticists, chemists, sociologists and mathematicians.

Originally, Mordin's team was merely studying population growths to see if the genophage was still effective and designing possible pre-emptive strategies should the krogan regain their numbers. The study soon changed when the STG team discovered the krogan were naturally overcoming the genophage. The only option the team could agree upon was to design and implement a new genophage that, as Mordin maintains, would limit reproduction to a viable level for the krogan to survive; otherwise, a war could result that would likely end in the complete genocide of the krogan. Not everything went as planned, though; one botched mission to disperse the modified genophage in an area of Tuchanka resulted in injuries to his face and right cranial horn.

Despite the hardship, Mordin would remember those days fondly, devoting his time to endless scientific research and discovery with people he respected and admired. But by the time the mission was complete, the team had gone their separate ways. Mordin himself, despite defending his decision as the only option, found the ethics of the project disturbing and even turned to religion to find some peace. The differing, sometimes contradictory, nature of religion led him to have a crisis of faith and left his worries unresolved.

After this experience, Mordin devoted his time to building a clinic on Omega, finding it easier to just heal people. He found himself unnaturally suited to life there, as he pulled strings in the STG to have some military-grade mechs defend his clinic. Generally, he found it simpler to deal with problems himself, easily killing any Blue Suns or vorcha attempting to intimidate him. His reputation soon grew and the Blue Suns learned to stay away from him. Even Aria T'Loak would grow to like him for his casual ruthlessness. He only returned to Tuchanka to do follow-up work, ensuring the genophage was effective. Though others could have done it for him, Mordin felt he should see the damage he inflicted, finding it cowardly to simply walk away.
