So originally it was Apollyon, which I found the definition as "The guard of abyss" (I couldn't find where I saw the definition though, which is very weird). And it's quite close to the meaning of my Chinese name. So I started using it as my game tag. one day I made a typo. It became Apollyn. And it becomes a very useful name as people don't use it often so I can register using that name easily(Well at least easier than other names I like).
