AFK - Imperian Online Help

15.12 AFK

There is no strict rule when it comes to players being AFK. AFK stands for Away
From Keyboard.

This does not preclude the strict rules outlined in HELP TRIGGERS. 

It is generally considered in your best interest to be active at your keyboard
while you are playing in Imperian, as you leave yourself open to theft, death,
starvation, and various other nasty side-effects.
