A Trade was an event when two Abyssin tribes met in the deserts of Byss. When two tribes met, usually at an artesian spring, either a Trade or a Blooding ensued depending on the amount of food or water present. If food and water was abundant, a Trade was called where the two tribes swapped everything from gaunts, weapons, and young males and females.
