Publisher's blurb:
A strange light appeared in Realmspace – found to be a new system. The Marbey family are wealthy Whaterdavian merchants who trade with various Realmspace planets. They hired Gallan Coppernight to find hearty adventurers to escort the ten Marbey Siblings into Wildspace on exploratory journeys.
During recent journeys, a celestial navigation chart permitted the adventurers to explore the system, Telthyspace. During the exploration, they encountered other explorers - modrons, illthid, devils, and githyanki. The locals on all of the tiny planets were from the Ares nation of Savelor. The locals were friendly and willing to establish trade, but informed the adventurers of a hazard. They spoke of their nation's very aggressive military, that patrols local Wildspace with metal-plated ships.
The adventurers learned one of the key ingredients of the metal plating, called Arcanite, is Gutted Iron and it can be found in Graak-on-water. Navigation charts were obtained, and a shortcut to Graak-on-water was found.
