This isn't an adventure. Instead, it introduces an ancient group called the Ravens of Despair who follow, or are drawn to, sorrow, despair and defeat wherever it takes place in the universe. Understanding their origins, nature and capabilities, you can then incorporate them into your own adventures - and to get you started, there are some ideas, some plot seeds, to build upon or draw inspiration from.
The creatures known as the Ravens of Despair were made by an even more ancient bunch called the Alturons, creatures of pure thought who needed to have some physical alter-egos or avatars to interact with the real world. Specifically, they made the Ravens because they found the universe to be a troubled place. Their intention was to make creatures that could absorb sorrow and despair... unfortunately, they botched it and although the Ravens can feed on such feelings, they intensify them for whoever was feeling them in the first place.
We read about their nature and how they function, what they look like and plenty more. There's a character sheet for them and notes on how they can be detected and perhaps even dealt with... maybe. You can also find out which races particularly dislike them, and which ones they tend to avoid (Daleks, for example, as they prefer to destroy rather than causing distress to their opponents!).
Finally there are three adventure outlines and notes for a two-part story arc than involves the Ravens. They are quite ingenious and include a mysterious retreat patronised by celebrities who want to shake off the blues or additions, a far future successor of New York where the annual Founders Day celebration is now a somber Day of Mourning, and a prison ship drifting in space full of panicking prisoners... and finally a rogue Alturon shows up, causing chaos for the Incas and others. Plenty to get to grips with here.
It's an interesting concept with a strange race that could serve as recurring opponents, or just the basis of a single adventure.
