Wolves That Walk Alone 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.

The Huntress and the Spartan by red october700 reviews
Two years adrift in the middle of nowhere. Two years of doing nothing. When a sudden wormhole appers and sucks the DAWN into it, it spits them out over a crazy new world. A world with it own problems that may need a SPARTANS helping hand. This is my first story. Expect mistakes, and this is only part one of a three way crossover. Constructive criticism is welcome.
