Raised as a slave in the Darkoath camps of Aqshy, Kiri dreams of a better life. Of a city of wonders, the place of her birth... Lifestone! She despairs of ever reaching it until a fateful day arrives when her barbarian captors are attacked by Sigmar's noblest warriors, the Stormcast Eternals.
Seizing her chance, Kiri flees through a mysterious realmgate that takes her far from the fiery lands of Aqshy. She arrives in the realm of Ghyran and finds the city of Lifestone. But a curse lies on this place, withering its noble spirit.
Her path leads her to a special group of children who, like her, are realm-marked - the prophecised saviours of Lifestone. There's Thanis, the fighter; Alish, the inventor; Kaspar; the sneak and Elio, the healer. But dark forces are allying against the children and will do anything to stop them achieving their destiny.
