You are only allowed to use alphanumeric characters.
It is forbidden to use:
- DEV or GM titles (eg. GM Joe)
- names or expressions which can be offensive to other players
Once you proceed you will not be able to change your name, but that name will be connected to your account, even if you delete it. Nobody else will be able to use it. You could, for example, delete Jack Miner and then recreate him, safe in the assurance that no one else will be able to take that name.
The Perpetuum Team reserves its right to block or delete any name which is deemed inappropriate.
