Thane Krios is a drell assassin, rumored to be the most skilled in the galaxy. Unlike most assassins, who prefer to snipe their targets from a distance, Thane prefers to get up close and kill his target personally, utilizing a mixture of stealth, firearms, hand-to-hand combat and biotic abilities. Despite his profession, Thane is a deeply spiritual man who prays for success in his missions, and asks for forgiveness after each kill, even going as far as to ignore those in his immediate vicinity until he is finished doing so. Thane was born in 2146. At the age of six, his parents gave him to the hanar to be trained as an assassin, as part of the Compact between the two species. He made his first kill at twelve. He reveals he is slowly dying of a disease which is later revealed to be Kepral's Syndrome. He joins Shepard's suicide mission against the Collectors, perhaps hoping to die in the process, which he feels will redeem him from his past evils. He also has the eidetic memory native to his species; the ability to perfectly recall every single act of murder he committed over the years. Thane is a possible romantic interest for a female Shepard. Appears in ME2. In ME3 Thane appears in case he survived suicide mission in ME2. -masseffect.wikia.com
