Warstalkers

The Warstalkers are a Loyalist chapter of the Adeptus Astartes located on the farthest edge of the Segmentum Pacificus. The Chapter is one shrouded in mystery and has made it their purpose to stay secluded from the greater Imperium out of shame. Their shame being their Primarch Horus Lupercal. The chapter has gone to great lengths to keep detailed records and are one of the few that know the whole of the Imperium's dark history. Their chapter has rejected the Codex Astartes and its limiting of chapter strength; relying still on the doctrines of the Principia Belicosa.
