Roads Paved in Shadows by
AlbertG reviews
"We don't have information on the numbers yet, sir," one of the commanders answered quickly. "It's not the Cylons. The Thirteenth Tribe is attacking us. We're at war with Earth." Adar was completely stunned that emotion quickly turning into a burning rage. "But why?" he snarled as his rage turned into a need for vengeance.

New Allies by
Riker's Beard reviews
This is a rewrite of my earlier story "First Contact", a crossover between Battlestar Galactica, Men in Black, Babylon 5, Farscape, Doctor Who, and Hitchhiker's guide to the Galaxy. There also are minor references to ALF, Star Wars, Discworld and a number of other shows, books, and movies. From a BSG point of view, the story diverges from canon at the discovery of New Caprica.

This is a spinoff story. It takes place after "But a somehow a most melancholy" and" Hunted Tribes". Please read those before this bit of work. I will not be recovering those stories, but re-reading them will help you fallow this story. This fiction also will be slow on the combat action.

A Critique of Heathenism's Effects on Mankind by
Cotto reviews
As a sequel to my work "S. H.", Helena Cain reacts to her "wife" Gina's betrayal, with very negative consequences and also is profoundly confused, due partly to her own inevitable ignorance about how things really work. Her society is intrinsically pagan; and there're a lot of problems for that kind of society that should be considered.

The Final Circle by
Sufficient Velocity reviews
This is a Babylon 5 centered tale. It explores a BSG style exodus due to the loss of the Earth Minbari war. It becomes a crossover with nBSG as of Interlude 1, and crosses with Firefly as of Interlude 2. Most B5 and BSG canon should remain unchanged, including EU. However, Firefly will mostly use series and film canon. Its EU began to expand after I had already merged the plots.
