Character separation:
The basic rule here, is that character knowledge separation must exist.
You are NOT allowed to use the knowledge gained with one character with
another character, regardless if they are same race or not. Since this is
impossible to demand in some cases (if you know a zone, you know a zone,
for example), we usually limit the "knowledge" definition to things
like knowing where players are, where dropped objects are, where corpses
are, what players are playing etc - dynamic knowledge.
To _help_ enforce this, we have some rules regarding how long you have to
wait before switching characters. These rules are automatically enforced
by the login code. NOTICE that adhering to the following rules don't exclude
you from the above mentioned basic rule of character separation.
