About this game
Lloyd grew up never knowing his real parents, living with his sister Trina in the border town of Aslint. He hunts and works as an artificer, while Trina has just begun training as a priestess. Their quiet life shatters when Trina falls mysteriously ill. Lloyd soon learns that Trina carries demon blood, triggered by the presence of a sealed Demon Lord nearby. To save his sister from a worsening fate, Lloyd must find a way to defeat the Demon Lord—before she transforms into someone unrecognisable.
Travel the richly detailed world, full of diverse characters, each with their own stories and quests to discover. Craft items and upgrade your gear to grow stronger. Converse with the townsfolk to gather any information that could help Trina, whose condition worsens as the demon blood within her awakens. Venture beyond the town’s borders and gather rare ingredients, explore dungeons, battle monsters, and level up. But after a long day’s adventure, don’t forget to return and tend to Trina's growing thirst for mana.
