Solitaires are the strangest and most dangerous of all the Eldar Harlequins. Called Arebennian in the Eldar Lexicon, they are doom incarnate, for they play the part of She Who Thirsts in the Dance Without End, and once their path is chosen no one can stay their hand. The Solitaires, as their name implies, are solitary individuals who roam the Webway, only joining a Harlequin masque for a battle or performance when the fancy takes them. Just speaking to a Solitaire outside the Dance is tantamount to death, for he treads the Path of Damnation, his soul forfeit to the Chaos god Slaanesh. Indeed, a Solitaire's role is afforded the utmost fear and respect by other Eldar, for only the bravest, strongest and most incorruptible of their race could play the part of their greatest nemesis and remain sane. Like all Harlequins the Solitaire wears a holo-suit during performances and in battle. Where other Harlequins are garbed in vibrant, bewildering domino suits, the Solitaire wears an austere hooded coat to disguise his appearance, revealing his Daemon-faced mask only moments before he strikes down his foe.
A Solitaire is outside a Harlequin Masque, and roams the universe alone. These solitary Harlequins represent the monstrous pride that led the competing heroes on their dangerous quest; an aspect of Slaanesh herself. The organisational structure of a masque hail from ancient days, when Cegorach's devotees were theatrical performers first and foremost. Since the Fall, a place has traditionally been reserved in a masque’s structure should a Solitaire lend their considerable abilities to a cause, but they are otherwise unchanged, centred around three distinct Troupes: the Light, the Dark, and the Twilight. Should one of the dreaded Solitaires deign to join a battle, they can slaughter entire enemy regiments in impossible displays of martial prowess. Solitaires are incredible warriors, able to move faster than the naked eye can follow. Their impossible acrobatics are such that no blade can strike them, nor bolt or blast find its mark upon their flesh. In battle they are utterly lethal, their scything kicks and hammerblow punches coming so fast that most foes are dead before they even realise the fight has begun. Indeed, each individual Solitaire is the equal of a host of lesser warriors.
Solitaires are the strangest of all Harlequins. They conceal themselves amongst craftworld or Commorrite society, hiding their true nature as they wander from place to place. Only occasionally will these dread figures reveal the monster that lurks beneath the facade, joining a masque for a performance or battle before drifting on once more. At such times they speak and are spoken to only in ritual form, and are feared by most Eldar as an ill omen. This mien of horror stems from the fact that, alone among the Harlequins, the Solitaire plays the role of Slaanesh. As a result, the Solitaire's role commands ultimate fear and respect. It also makes him the most dangerous of all Harlequins, for a Solitaire treads the Path of Damnation, his essence doomed to be devoured by She Who Thirsts. In 666.M33, it was the Masque of the Dance Without End who gave the first ever performance of the Fall. Their audience were horrified, not least by the disturbing figure of the galaxy's first Solitaire as she brazenly bestrode the stage. Knowledge of his soul's forfeit means a Solitaire will ensure the cost to his foes is dear indeed before he meets his end. Despite the dark fate that awaits them, it is said that Solitaires are touched by the Laughing God -- that they have his insight into the Fall, and even the nature of the universe. Many Eldar believe that to speak to a Solitaire is to invite a grisly demise, and that should an individual accidentally address or touch one of these lonely beings, they would be better to take their own lives there and then.
The first the foe knows of the Solitaire's onset is a shimmering blur of light and colour streaking through their ranks. Then the killing begins. Soldiers fall, eyes widening as heads are severed, throats opened, and hearts pierced. Blood falls like monsoon rain in the wake of a killer too fast to be seen. Only when he pauses for a moment amid the slaughter do his victims get a glimpse of their executioner -- a domino field swirling around his lithe form, his grotesquely masked head tilted at a curious angle as he regards those he hunts. This is the Solitaire, and as he leaps into motion once more, his victims' deaths are but seconds away. None, even amongst the Harlequins, know the limits of the Solitaires' abilities. Tales exist of these supernatural killers running up sheer fortress walls, spilling from the shadows inside locked bunkers, even slowing time itself. How much is hyperbole and how much the truth, few can say for certain. To those who stand in the Solitaire's path it matters little, for their deaths are assured either way.
- Holo-Suit - In battle, Holo-Suits transform Harlequins into dazzling blurs, their outlines exploding into blizzards of light that leave the foe’s aim confounded and their thoughts bewildered.
- Harlequin's Caress - This device sheathes the wearer's hand in a deadly power field.
- Harlequin's Kiss - Plunged into the victim's body, this weapon reduces their innards to meat slurry in moments.
- Flip Belt - In contrast to the lumpen and crude technology of lesser races, the flip belts of the Harlequins are things of grace and beauty. Appearing as an ornamental belt, usually inlaid with precious metals and inset with glorious gems, it is actually the casing for a complex anti-grav generator so advanced that it would totally baffle the Adeptus Mechanicus. In their performances, flip belts enable Harlequins to jump and pirouette with preternatural grace. On the battlefield, they enhance their already formidable deadliness. The belt itself is so light that it does nothing to inhibit the wearer, in fact it enables them to sprint effortlessly across rubble or scree without slowing and to leap and weave through deadly melees with the grace of the finest dancers.
