Valhalla

Valhalla: Outpost 17-B
Valhalla makes it's first appearance in Red vs Blue in Reconstruction season.

Role in the plot
Valhalla is the crash site of the Pelican that contained Tex], Andy, Junior, Sheila, Omega, and The Green Alien. The outpost showed up several other times in Cahpters: 5, 13, 14, and 19. The Reds and the Blues (or Caboose) are to continue their training routines by order and gratitude of the UNSC.

Theory
Logical thinking could assume that Red vs Blue next season will be back to a slower style like The Blood Gulch Chronicles.
