Serpent's Den of Djarghul

In the shadow of the mountain range known as the Dragon's Spine lies a hidden dungeon, rumored to be the remnant of the dark sorcerer-king Djarghul's twisted ambition. Generations ago, Djarghul sought to harness the power of serpentine creatures to create powerful guardians and, ultimately, attain immortality. While his experiments failed, the residual magics and strange beasts remain. Adventurers seeking fortune, glory, or even a hint of forbidden knowledge are emboldened to delve into this accursed lair, hoping to uncover long-lost artifacts or powerful lore.
