The Space Owls Chapter, or the ‘Sova Noctis’ as the warriors of the chapter often refer to themselves, are a non-codex compliant chapter of space marines. Inheriting the Gene-Seed of the Raven Guard’s Primarch, Corvus Corax, the Space Owls are supernaturally stealthy warriors who excel in stalking their prey, then unleashing sudden ambushes and devastating close quarter assaults.
The Space Owls Chapter was created by the excellent creator of Grimdorables who first came up with the idea and look of the chapter. His excellent idea and artwork inspired me to ask about expanding this Chapter into a small Index Astartes article and here it is. I highly recommend going to his Instagram and Patreon to support him if you can.
