In my campaign world the Eladrin people believe no other race has the right to detain or imprison them. They go their own way and take care of their own criminals.
Non-Eladrin authorities might hold one temporarily with a pit, windowless room, bag over the head, etc., but long-term imprisonment is as like as not to bring a Ghaele of Winter down on their heads when word gets around.
Of course, in Eladrin cities they have magic circles, living stone cells, floating prisons, prisons of eternal slumber, astral entrapment and many more creative ways of dealing with transgressors.
