Seven rings were made long ago in the days of the Queens of old, seven highly magical rings to help a ruler to rule, but they proved anything but helpful.
A small, enchanted chest, 2 feet on a side. It is of some dark wood with fantastical images graved upon it. Worn leather straps act as hinges and a simple toggle keeps it closed. Anything placed within it, with the lid closed, becomes accessible to anyone with one of the other 5 identical chests. Once it is taken out of any one of the 6, the chest is empty again. Perfect for passing messages or small items between widespread groups, such as ships at sea and their ports of call or generals on the field of battle.
