An Ancients device sparked the Core Expeditions, journeys that would take the Zhodani closer to the Galactic Core than any other known civilisation. Spanning thousands of years and costing trillions of Credits, the Zhodani are now over halfway to the centre of the galaxy. However, not all is well, and the Consulate has been keeping secrets. The Travellers may be the ones to solve an interstellar catastrophe before it reaches Charted Space. 

The Core Expeditions takes Referees and Travellers through the eight expeditions, discovering stellar abnormalities, ships, vehicles, animals, robots, and more. This book covers the extensive history of the expeditionary forces, the beginning of the Core Expeditions, and includes notes on running an expedition as a Traveller campaign. At the heart of many Traveller campaigns is the desire for exploration, to seek new worlds and meet new peoples. The Core Expeditions allows you to do just that, taking part in any expedition, including those that have spread throughout the path coreward like water bursting from a dam.
