[Groups help] free
Syntax: free 
   If you love it set it free,
   If it returns,
   It was meant to be.
This may not quite be true in Shattered Kingdoms.  However, free allows
characters who control a pet of some sort to release their hold on it.
This can be done if you wish to purchase a new pet, or have lost the old
one.  After the pet is free, it will completely ignore its former master.
