Abyss of Argus

(This is not a World of Warcraft fanfic, nor is it a From the Abyss fanfic. If you don't like it, don't read it~Thank you~) In a world where every corner has been explored, the only remaining secret is the large cave "Argus". I don't know where it continues, but the bottomless huge vertical cave is inhabited by wonderful and strange creatures, and there are precious relics that cannot be made by the intelligent creatures of the current continent. The incredible appearance of "Argus" attracts intelligent races and drives them to embark on adventures. In this way, adventurers who have challenged the large cave many times have gradually gained the title of "explorers".
