Prince Xantor is hunting in Hazdrubel Woods when his sister Canastria finds him. Their younger sister Ameliana has not come home whilst travelling with Balovan the trader. Xantor is sent to find her, and the trail leads out of Esipiona, through Sapharia, and toward the vastness of Dasteria.

You read as Xantor. You choose the road, the fight, and the gear. Canastria tracks beside you. Cousins, armourers, and old names of the house will help or hinder. There are beasts in the hills, Exiled in the mountains, and something worse on the wing: Dragon Elves, and the Netherflights they ride.

Finding Ameliana is a gamebook. 

Three hundred and fifty pages. 

Dice, swords, bows, and a few hard deaths.
