Creation/Management/Remote Control
From Graal Bible
RC stands for RemoteControl. The Remote Control is a tool that comes with graal and can be used by high level staff on all servers to manipulate major aspects of the server. With the RC, you can, with the correct rights: Manipulate levels, NPCs, classes, server options, bans, player attributes, account information... However, most of the items listed are not available to the average person. You must have gold and/or vip to access RC on Gold Servers or Hosted/Private Servers.
If your RC is messing up (Disconnecting you from servers) simply open the Graal Client, log in and go to the Updates tab and click on RemoteControl2. Then Click reinstall and RC should be fixed.
