Mordin Solus is a salarian scientist, brilliant yet also a competent soldier due to his membership in the salarian Special Tasks Group earlier in his life, Mordin Solus possesses a hyperactive and eccentric personality, a rapid and stilted manner of speaking, and (as with all salarians) a flawless autobiographical and eidetic memory. He was a key member in the science team that researched the remodification of the Krogan Genophage, an action that he feels guilty about but considers the best possible solution to a once growing problem. Mordin believes in acting in the best interests of the galaxy; his scientific work is governed by strong moral standards and unquestionable respect for all forms of life.
