A ritual meant to summon the wisdom of the First King went wrong. Instead, the Demon King answered the call. Now monsters roam across Primordia, and only a magical barrier keeps the capital safe. This protection exists thanks to four ancient artifacts: the Binding Crystals. Only one crystal can be wielded by a hero at a time — while the other three remain in the kingdom, sustaining the barrier that prevents a full-scale invasion. You must decide who goes, when to depart, and how to face a world that is constantly changing. Features Real-time Action RPG Combat Fast-paced combat controlled with the mouse and abilities assigned to Q, W, E, and R. Full controller support with an adapted control scheme. Four Playable Heroes Each hero has unique skills, special mechanics, a distinct personality, and different interactions with the world and the weather. One Crystal, Strategic Choices Only one hero can explore at a time. Choose carefully — not every hero will always be fully available. Day & Night Cycle and Dynamic Weather Sun, rain, night, and other conditions affect hero availability, camp events, bonuses, penalties, and more.
