A peerless practitioner of lethal shadow magic, Shieda Kayn battles to achieve his true destiny—to one day lead the Order of Shadow into a new era of Ionian supremacy. He wields the sentient darkin weapon Rhaast, undeterred by its creeping corruption of his body and mind. There are only two possible outcomes: either Kayn bends the weapon to his will... or the malevolent blade consumes him completely, paving the way for the destruction of all Runeterra.

Kayn wields an ancient weapon and fights Rhaast, the darkin within it, for control. Either the Darkin will triumph, or Kayn will master Rhaast and become the Shadow Assassin.
Darkin: Heal for a percentage of spell damage dealt to champions.
Shadow Assassin: For the first few seconds in combat with enemy champions, deal bonus damage.


As an honored Ordinal of the Demaxian Empire, Kayn relentlessly hounds the crew of the Morning Star, hoping to recapture Sona and learn the secrets of the legendary Ora Gate. He bickers constantly with his sentient alien scythe, Rhaast, whose own motivations are far more dire than Kayn could ever realize…

Rhaast was once an archon of light, a beacon of order… and now he is little more than a weapon in the hands of Kayn, an ambitious demi-god of dusk seeking true godhood. The two war within Kayn's own body, each determined to overthrow the other and lay claim to true divinity.

Kayn and Rhaast are forged anew in the crucible of their clash. No longer are they a mere weapon, a mere demigod— they are forces of nature, warping each other and the raw energy around them, each hurtling towards a victory sure to shake the firmament itself.

The communion was nearly complete. Kayn could feel the Blood Moon demon writhing within. It was then that the Snow Moon assassins struck. Stolen away from that temple into theirs, Kayn was inducted into the Snow Moon Order, their ancient ways piercing and unfamiliar. Only time will tell if their taming of his spirit holds.

Kayn wields his music like a weapon—both as himself and as his demonic alter ego, Rhaast. Though he's got all the training of a pop music prince, his bad reputation after the breakup of his last band made him an industry pariah. Determined to spite the haters, Kayn joined HEARTSTEEL only to find creative partners (and friends?) he might actually trust.

Co-captains of the Assassin Club, Kayn and Rhaast are an embodiment of Babylon Academy's tactics. Kayn lulls rivals into a false sense of security before Rhaast explodes with overwhelming force, pummelling opponents into submission. Rhaast's diligent work ethic is the real reason they're here at all, as Kayn's aloofness irks all of his classmates.
