Taken from my EoY:

It's basically a name I came up with. Back in Grade 5 a friend and I were trying to come up with cool sounding names for something I can't exactly remember. He came up with the names Aklan and Emokichuk. I tried to come up with cool names as well but he didn't like my name ideas like Gatradis and Kyudis. Evastio was the only name he found cool. When I was making my EoFF account I wanted to make my name a cool one that nobody else would be using. Evastio was one of the first ones that came to mind so I decided to stick with that name.
