The master of a house can instruct his guards and gatekeeper about which other people are to be welcomed into the house. This is done via the FRIENDS command.
friends list - Display current friends friends add <name1> <name2> ... - Give someone free access to the house friends remove <name1> <name2> ... - Remove the welcome status
These commands must be used while in the same room as your valet or guards.
NOTE: You are not allowed to add players of the opposite side of the race war.
Failure to adhere to this rule will result in immediate annhilation of your legend home as well as possible demotion.
