Deepnight Revelation must find a way across the Great Rift, or backtrack hundreds of parsecs. There is a way; a chain of isolated star systems and deep space refuelling points, but it is hazardous in the extreme. The Travellers have good reason to believe the crossing is possible another expedition passed this way before them. As the Travellers make their crossing they come upon an extremely rare phenomenon a frozen star, its temperature so low that it has a solid crust of exotic materials. On the surface is an obviously artificial object someone landed here and built a structure! If the Travellers dare to follow they will learn more about the expedition that preceded them.
