"Even if they hide in the darkness and the mists of Ulgu, the enemies of the God-King will not escape me."
— Elinor Borealis, Knight Zephyros.

While chaos worshippers and traitors inside the city of Port Stellis regularly get assassinated by Nocturne, the enemies outside the walls of the free city aren't safe from being murdered by the forces of Order either. Sometimes, when his vanguard rangers identify a threatening character looming around in the Coast of Fleeting Hopes, the Lord Aquilor Andras Silverblade sends one of his best agents on a hunt, a female Knight Zephyros known as Elinor Borealis, the huntress of shadows.

Elinor usually work along with her vanguard ranger comrades, patrolling and exploring the region, but when she when she receives an assassination mission, she ventures alone in the wilderness. While all Knight Zephyros are blessed with superhuman senses, Elinor has to face a peculiar challenge that the others usually don't: the landscape of Ulgu is treacherous and full of misleading illusions. The darkness murmurs lies made credible by faint hints of truth. Paths are never fixed and always change, so it is no use memorizing them. And shadowy creatures prey upon the confused and the lost who have been led astray. Many travellers and warriors have disappeared in the mists.
However Elinor possesses an advantage: in her mortal life, she belonged to a clan of humans hunters in Ulgu. She is a native of the Realm of Shadows, therefore she understands the land better than most and she knows how to thwart the illusions and how to navigate in the mist and the dark. She can even use them at her advantage against her foes, slaying them with greater ease.

Lately, Elinor has been ordered to monitor the movements of a chaotic army gathered in the north: the Court of all Sins.
