An invasion by the Darkborn from the Dark Realm shattered the peace of this magical world. The Darkborn destroyed the core magic, scattering its power and sealing it across the continent. The land was plunged into darkness and chaos, magic gradually withered, and life suffered. Centuries later, you, an adventurer who accidentally discovered a fragment of magic, will embark on a journey to explore the continent, collect magical shards, and restore magical order to the land, carrying this faint hope with you.
