The kingdom walls stood hundreds of feet high, carved from enchanted stone blackened by centuries of monster attacks. Beyond them stretched the Frontier—a vast, untamed wilderness where towering forests, crystal valleys, cursed swamps, ancient ruins, and dragon-haunted mountains hid countless mythical beasts. Few who entered returned unchanged. Every adventurer knew the rules. Hunt. Survive. Adapt.

The stronger the beast, the greater the reward. Some chose to slay the creatures for rare materials, while others sought to tame them, forming lifelong bonds that could shape the fate of kingdoms. Legends spoke of World Beasts—ancient creatures so powerful that earning their trust could change history itself. This morning, the Frontier Gates creaked open.

Dozens of adventurers, hunters, beast tamers, scholars, and mercenaries gathered beneath the massive archway, each hoping to make a name for themselves. Guild banners fluttered overhead while merchants shouted last-minute offers for potions, traps, enchanted weapons, and survival supplies. A silver-haired guild master stepped onto the stone platform overlooking the crowd.

He paused, scanning the sea of eager faces

With a thunderous groan, the colossal gates slowly opened.

A cool wind carrying the scent of pine, damp earth, and distant rain swept through the crowd. Somewhere deep within the endless wilderness, an enormous roar echoed across the landscape, followed by dozens more answering calls.
