Mine is historical. I am a history buff, always have been. One of my favorite eras to study is the WWI and WWII era. My username, in minecraft, is LiveInInfamy. This comes from FDR's speech after the pearl harbor bombing. From the speech: "...Yesterday, December 7th, 1941 -- a date which will live in infamy -- the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan..." I saw the phrase "A date which will live in infamy," and I thought that sounded pretty cool and decided to make it my username. Overtime, on other servers, the people I worked with would call me Lively for short, and I made that my name for the MCSG website.
