Emerald's characterbase was a combination of characters from Emerald as well as the shut down Konried server.
Characters who came from Konried whose names were already in use on Emerald have a "-K" appended to the end of their names. These names transfer to Gemini. If another character already existed on Markov before the server merge and had priority over the Emerald name, a "-E" was appended to the end of the Markov's character name. Outfit names followed a similar rule. See Gemini for more information on character and outfit naming rules and how to change them if they have a "-M" or "-E" appended.
