Orbus ring

An orbus ring was a type of magical jewelry that improved the speed at which a mage could navigate a spelljammer while at its helm.

Description
These extremely sought-after rings were carved from ivory intertwined with platinum. Their power was drawn from residual magic of the remains of an orbus.

Powers
When not at a spelljamming helm, the wearer of an orbus ring experienced no magical effect or enhancement of abilities.

History
An original, and more powerful set of orbus rings were crafted long before the 14 century DR, although the secret of their construction was lost for over a hundred years. However, a cache of these rings were eventually discovered on the Rock of Bral. The only known dealer of these 2 generation rings was the spelljamming expert, Gamalon Idogyr.
