[Groups help] order
Syntax: order  
Order allows you to control your charmed followers, whether they are other
characters, mobs, or pets.  You are responsible for their actions while they
are under your command.  Others who attack your followers will find themselves
fighting you as well, if you are set to auto assist.
Most charmed creatures will lose their aggressive nature while charmed so that
they do not attack the one commanding them.  Those who are charmed will have
trouble casting spells due to their mind being overwhelmed.  Attacking your
follower will break the link between you.
