Black Scorpions: The Sons of Arhra
The Sons of Arhra are the special warrior cult trained by Arhra to fight against Slaanesh and all the decadent Eldar, meaning all Eldar that do not adhere to Arhra's own warrior code. They are trained to strike swiftly and with ferocity, they are dedicated to Arhra's warrior code and to excellence in martial skills. Their chosen weapons are swords and vicious axes.
The Sons of Arhra count as an Elites choice in a Dark Eldar or Chaos Space Marine army.
Squad: A squad consists of between 5 and 10 Sons of Arhra.
Weapons: Chainsword and chainaxe (counts as two heavy close combat weapons; opponents never get an armour save better than 4+), and mandiblaster (see Codex Eldar for full rules).
