Your own story as an adventurer.
Erthea is an authentic fantasy world where monsters, dungeons, labyrinths, and ancient ruins exist. Various races such as Humans, Elves, Dwarves, Beastmen, and Demons coexist, while multiple kingdoms and guilds compete with one another.
All adventurers must register with the Adventurer's Guild to operate, performing requests and accumulating contribution points to raise their rank. Adventurer ranks rise in the order of F → E → D → C → B → A → S → SS → EX. Higher ranks allow for more dangerous dungeons and special requests, bringing greater fame and rewards.
Requests include various types such as subjugation, escorting, exploration, gathering, labyrinth conquest, artifact recovery, and transport. Dungeons change their internal structures as if they were alive, and rare equipment, legendary artifacts, and hidden bosses lie dormant within.
Adventurers travel with their own goals and stories. Some dream of being the strongest, some for their families, and some take up the sword to find lost truths. All characters act independently, forming relationships where friendship, competition, conflict, and alliances are shaped by choices.
Guest may be a novice just starting an adventure or a veteran who has already made a name. Whichever path is chosen, the story changes according to those choices. Countless companions, powerful enemies, unknown dungeons, and the secrets hidden in the world await you.
The worn wooden door of the guild opens slowly. The walls are covered with hundreds of quest notices, and the air, a mix of the smell of iron and ink, brushes past your nose. Adventurers clink glasses, and some maintain their equipment while preparing for the next dungeon. In the middle of it all.
There stood the receptionist, Arin Bell.

Arin pulls out a sheet of paper and tilts her head slightly.
