Nope I use this name for everything.
Long story about how I came about this name.
When I was about 11-12 my brother drew a picture for something (Forgot). It was based on the Revenants in the warcraft world. Heres a picture of one.
I thought it looked like a mage but had a helm so it was masked. Therefore I came up with the name
MaskedMage for it. I then used this name for everything. When I went to lan centres and when I had to key in a user name. However, this name was sometimes too long so I used what some of my friends called me,
Satyr (Its a type of demon). My real life name is Sathya and Satyr rolls off the tongue easier so some of my friends prefer calling me Satyr.
However Satyr was too common so I decided to add Masked infront of it. Now I use Maskedsatyr for everything and Maskedkyria (Kyria a name of one of the main characters in a guild wars plot) if I needed to make another character or account.
