Aromulus Gionni was a Capitol model mopping to be a fake victor for The 54th Hunger Games at age 18. He supposedly won these Games by being a career, meaning that we probably was skilled in close combat and had brute strength as well. He died in 65 ADD due to alcoholism at the age of 27.
Just like Augustus Braun, his name has a Roman origin, Romulus was believed to be the first king of Rome.
However, aroma may refer to perfume, one of the luxery items from District 1.
He an Augustus Braun, another fake victor posing for the Capitol both died at the age of 27 for their own reasons.
