Origin of name
Tigrounette and Melibellule were leaning towards "Mice Studio" when Ley suggested "Atelier 801", as a reference to the special room 801 which was originally created for testing purposes. The admins liked the idea since it made a reference to the players, so they decided to choose that name.
