Authentication

Players will log in through the login server and be given an access token upon successful authentication. After receiving a list of available game servers, they will use their access token to connect to a specified server. All game servers will query the control server to check if the token belongs to a player that is already online. If everything checks out, the player's data will be loaded by the connected game server, and the player is allowed to enter the game world.
