A couple of years ago I had a friend. Okay, maybe a little more than a friend. Her name was 'Yindoom', and she passed away. Not too long after, I started playing League of Legends, and I wasn't allowed to have my summoner name be the same as my username, for some reason. So I called myself Yindoom, in her memory. I met a few people in the game, and they started calling me Yin, even though I was called Dragon pretty much everywhere else. In the end I decided to adopt the name for myself permanently, to keep her memory alive and all that jazz.
