I wanted a word without symbols or numbers, almost impossible to have a gamertag that way that isn't taken. Narcodium isn't a real word, but when I thought of it I was 13, it was 1996-97 and I was taking an interest in ( not taking ) narcotics and their effects on the mind. At the time I dubbed the euphoric state some people experienced on narcotics as "narcodium"... Years later when I signed up for Xbox live, no one thought of it or coined it so used it... I still like it, sounds more of an alien element to me now
