Dark Eldar x Craftworld Eldar: Harlequin

"The Harlequins, or Rillietann, are a unique subset of the Eldar race, who split their time between being talented battlefield fighters and theatrical performers. They exist outside of normal Eldar society and hold no allegiance to any Kabal, Craftworld, or other form of authority other than to their own belief in the Eldar deity Cegorah the Laughing God" ~ Lexicanum
