Ask not the sun why she sets
Why she shrouds her light away
Or why she hides her glowing gaze
When night turns crimson gold to grey
For silent falls the guilty sun
As day to dark does turn
One simple truth she dare not speak:
Her light can only blind and burn

No mercy for the guilty
Bring down their lying sun
Blood so silver black by night
Upon their faces pale white

Cruel moon, bring the end
The dawn will never rise again

An unyielding avatar of the moon's power, Diana wages a dark crusade against the sun-worshiping Solari. Though she once sought the acceptance of her people, years of futile struggle shaped her into a bitter, resentful warrior. She now presents her foes with a terrible ultimatum: revere the moon's light, or die by her crescent blade.
Though she was born to the Solari, Diana's inquisitive nature set her apart from her brethren. She had always found solace[*] and guidance in the night sky, and questioned the dominance of the sun in her society. The Solari elders responded to her challenges with only derision and punishment. Diana remained convinced, however, that if she could find evidence of the moon's power, the elders would listen to reason. For years, she studied Solari archives in solitude until she discovered an encoded message hidden in an old tome. This clue led her to a secluded valley on Mount Targon where she unearthed the hidden entrance to an ancient, sealed temple. Inside, among aging relics and faded murals, she found an ornate suit of armor and a beautiful crescent blade, both inscribed with sigils of the moon. Diana donned the armaments and returned to the Solari elders that night. She declared that the artifacts proved others had once worshiped the moon as she did. Her discovery of evidence challenging Solari dominion shocked the elders. To Diana's horror, they pronounced her a heretic and condemned her to death. As the elders prepared her for execution, Diana's anger and sorrow overwhelmed her desire for acceptance. She lifted her gaze to the sky, calling upon the moon for strength. Lunar power surged within her and she shattered her bindings. Raising her relic blade, she turned and slaughtered the elders. With the temple in ruins behind her, Diana resolved to destroy all those who would deny the power of the moon.

"The sun does not reveal truth. Its light only burns and blinds."

Not all creatures of the night are the sort that lurk in the shadows. A select few leap headlong into the fray, leaving enemies begging for sunshine.

Diana, Scorn of the Moon, Revealed
Announcement made by NeeksNaman:[2]

The tide of battle is turning, summoners. With ceaseless aggression, powered and protected by the lunar light, Diana, Scorn of the Moon, controls and chases her enemies through the battlefield, leaving them no sunlight for solace.

Diana's high area of effect damage and defensive abilities make her an ideal jungler. Pale Cascade creates three orbiting spheres that detonate and deal damage to any enemy that comes close, while protecting her with a shield that absorbs any incoming damage. If all three orbs are detonated, the shield effect is refreshed, allowing her to absorb even more punishment. This destructive shield, combined with a cleaving attack from her passive, Moonsilver Blade, helps her deal out significant damage to multiple targets as she quickly tears through jungle camps.

Drawing power from the moon, Diana's kit revolves around her use of Moonlight to prep her enemies for an incoming attack. The breakneck pace of Diana's gameplay and her relentless chasing potential are driven by the interplay between Crescent Strike and her ultimate ability, Lunar Rush. A unique curved skillshot, Crescent Strike unleashes lunar energy in an arc, damaging any enemies in its path and simultaneously afflicting them with Moonlight. Casting Lunar Rush to teleport to an enemy afflicted by Moonlight will reset the ability cooldown while consuming all active Moonlight debuffs. Judicious use of Moonlight combined with accurate casts of Crescen Strike gives Diana incredible mobility and sustained damage throughout a long fight. While using Lunar Rush only in combination with Moonlight will give Diana the highest damage output over time, you may make a judgment call and accept the longer cooldown to either directly rush a vulnerable target or double tap a Moonlight afflicted enemy for heavy burst damage.

Diana's kit really comes together in a team fight. After initiating with Crescent Strike and Lunar Rush, she can follow up with Moonfall, drawing in and slowing all nearby enemies, holding them in range for Moonsilver Blade and Pale Cascade until Crescent Strike is ready again. The added durability of her shield helps her survive heavy damage, while the mobility of a Moonlight-enhanced ultimate helps her pursue and assassinate high-value targets. With the complex interplay of her abilities, Diana's got the potential to control the jungle while executing quick ganks and threatening enemies in team fights./spoiler]
