Stargate SG-1: The Fifth Race by i-defy-fate reviews
AU! Heavily inspired by the story: Project Blue Book by AmeliusTheAlteran. Elements of Halo will be here as well because I love the design of the ships, weapons and equipment they use. This is a story of what a united earth could accomplish when given a common goal. I plan for this to be at least 200-250K words. Starting chapter 2 expect to see 10k words per chapter. No pairings!

Wrong Place, Right Time: A Hero's Story by DLTA-BOT reviews
The journey of a hero doesn't always start where they expect. It doesn't always happen to those who expect it. Damon was never interested in being what SPARTANs represent: an implacable force for good standing as humanity's shield. Like most other third-generation SPARTANs, the war took everything from him. All he wanted was to return the favor. Sometimes we don't get a choice.

Wolves That Walk Alone (Hiatus) by TheManThatWalksTheAbyss115 reviews
There's always been growing legends in Remnant. Some of fearless warriors and others of horror, but there's one that's recently been picked up by the inhabitants. A legend of a man who was more akin to a wolf without a pack, barely speaking and doing his deed before leaving without a trace. After all... some people just want isolation rather than company.
