Characters are never deleted from the database on Shaman. This is a full record of every character since we first opened in 2009. Only part of the information is shown in the main view; to see more information, click the character's name.
If a player no longer wants a character, they can opt to make that character "playerless" by posting on the updates board. This means that the player relinquishes all rights to that character and offers it up stipulation-free to other players. Anyone can take a character listed as "playerless" in the Player field and do whatever they like with it.
If you want to offer up your character to others but have rules/stipulations about what they can do with it, do not make it playerless. Ask on the chat board instead if anyone wants to play it.
To find playerless characters, search "playerless" in the Player field. Claim playerless characters on the updates board. You can make up any information not listed in the database (e.g. personality, history, appearance).
