The Solitaire is the most singular and terrifying of all the Harlequins, a Player who has taken upon himself the one role no other dares perform, that of Slaanesh, the Great Enemy, in the myth-cycle of the fall. To dance the role of She Who Thirsts is to be forever severed from the rest of Aeldari society, damned and alone, and it is said that a Solitaire's soul is already forfeit to the very god he portrays.
On the battlefield a Solitaire is a blur of impossible motion, moving faster than thought, faster than sight, a whirlwind of the caress and the kiss that leaves a trail of the slain in its wake. No formation can hold against it, no champion can match it, for it dances a dance that mortal reflexes cannot answer. Alone among the Harlequins the Solitaire keeps no company and speaks to none, a solitary figure of dread even to its own kind. It is the sharpest blade in the Laughing God's hand, unleashed only when the myth demands a death that nothing living can prevent.
