Tomfoolery in Eberron
Murlocs are short, usually green or a shade of blue and/or black. They tend to group themselves into small tribes, usually ranging in size from 30 to 50, though some groups reach hundreds.
All groups have a single leader that they answer to directly. This leader is determined based off who holds their tribes item, which is usually a staff or some other such item.
Sometimes, new tribes will break off with a new leader and new magic item.
