From the Introduction (summarized):
This set of starship deck plans is composed of ten starships of between 100 and 1000 tons intended for use in adventure situations. The enclosed sheets present complete plans for each ship, drawn in 15 mm scale.
A set of 112 die-cut, illustrated cardboard counters is provided representing ships' crews, Imperial and Zhodani naval personnel, passengers, and other interesting character types.
Two booklets are provided. The first presents background material and supporting information for use with all the ships in the set. The other contains descriptions of each starship plus a collection of small craft.
