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.
