Harlequin - Enigmas of the Black Library: These artefacts are items of incredible rarity, ancient treasures that are carefully maintained and stored within the Black Library:Cegorach's Rose - Representing the barbed gift given in jest by the Laughing God to the crone Morai-Heg, Cegorach's Rose contains thorned monofilaments of shadowsilk. Existing in the penumbra between realspace and the labyrinth dimension, these shadowsilk strands bypass even the thickest armour as though it did not exist. Once within the body of the victim, the Rose's threads uncoil, a blossom of molecule-thin blades unfurling at the end of each. Thus, the foe is slain instantly as a thicket of bloody, bladed roses bursts forth within their chest.Crescendo - This masterwork shuriken pistol was first bestowed upon a Troupe Master of the Veiled Path. Supposedly, it was given as a gift by a wanderer of the Webway, who members of that masque claim was none other than the Laughing God himself. While many doubt the word of the Veiled Path in this, there can be no denying that Crescendo is a beautifully crafted and uniquely potent firearm. When the pistol's trigger is pulled, micro-distortion engines engage within its housing. The effect is to step Crescendo's wielder slightly ahead of time, accelerating weapon and wielder alike and allowing an impossible volley of firepower to be unleashed. Thus Crescendo lives up to its name, filling the air with a rising howl as it scythes down waves of the foe.The Laughing God's Eye - A pendant of rune-carved wraithbone, this potent artefact is said to draw the watchful eye of Cegorach himself. Psychic powers flicker and die in the pendant's presence, for the Laughing God will not suffer his children to be beset by the tendrils of the Warp. This aura of abnegation extends not only to the pendant's wearer, but billows like a concealing cloak to shield nearby allies. So does Cegorach watch over his followers, guarding them from the predations of She Who Thirsts.Mantle of The Laughing God - Every few decades, the Harlequins converge upon a particular craftworld, in search of a champion who will bear the mantle of the Laughing God in pursuance of some dire task. Whilst he bears the mantle, the champion will surely walk in dark and perilous places, but he will not do so alone –- the Laughing God was ever sentimental of his followers, and watches with keen interest those who do him honour.The Mask of Secrets - Many Aeldari believe the Mask of Secrets to be no more than a dark fable, and perhaps it would be better if this were so. Yet it is very real, kept within a shadowed vault deep within the Black Library. All who look upon this mask see distorted reflections of their own faults and failings, the slightest doubt or regret twisted into a horrific swarm of phantasms that scream and wail as they claw at the psyche of the victim. Those who wear the Mask of Secrets fear nothing while the mask remains upon their face, yet it is said that in the long run they must pay a terrible price for this temporary boon.Starmist Raiment - At first glance, there is little to distinguish the Starmist Raiment from a typical holo-suit, save that it is woven through with gossamer-thin strands of what looks like liquid silver. Yet when the wearer moves, they are engulfed in a shimmering cloud of refracted starlight that blinds and confuses the foe. This effect is magnified when the wearer moves quickly, the blurred glow swelling to become a blazing corona almost impossible to see through. So does the wearer mimic Aelos, the heavenly star flung by Cegorach himself, that smote Vaul's treacherous assistant Ghaevyll and blinded him for his deceits.The Storied Sword - An exquisite and perfectly weighted weapon, the Storied Sword has a starmetal blade and a tooled wraithbone grip. Inscribed upon the sword in minute script is the entire tale of the Fall of the Aeldari, as narrated by the Shadowseers. As the wielder of this weapon fights, they find their mind filling with images of that terrible time, impossible psychic snapshots of the greatest tragedy ever to befall their race. Driven into a killing fury by the horrors they have seen, the wielder fights all the harder, determined to prevent any such terrible events from transpiring ever again.
