1.) Characters MUST have a first AND last Faerunian name.
2.) No titles or 'ofs' in the name. Ex: Lady Insane Cow; Insane Cow of Daggerdale
3.) Keep names to "real" names of the time and setting. Barbi never lived in the Realms. Neither did Candi. These would be nicknames which are acceptable.
4.) Nicknames must be in quotes, although where in the name is not an issue. Insane 'Bovine' Cow and 'Bovine' Insane Cow are both fine. Please note that if you use " as opposed to ' to separate out your nickname it will cause trouble with people trying to send you tells.
5.) If you play a character that will be known only by their nickname, please post that in your character description field so that it's known to all that see you.
6. ) Do NOT use the name of any character that is closely associated with any novel, film, legend, celebrity, or sourcebook.
If you have any questions as to whether or not your chosen name is appropriate, ask a DM. We're here to help.
