Sanctuary of the Serpent

Description
"Scattered throughout the landscape you can see ominous entrances to vaults. The remnants of the elder races dwell in these deep dungeons. Enter the vaults to explore dark tunnels, underwater caverns and ancient halls.

''Solve puzzles to progress and uncover hidden treasures, all while fighting your way through fiends, demonic spiders, goblins, harpies and many more of the eldritch creatures that created these forgotten monuments.

''Each vault was a receptacle for the power of an elder race. The vaults contain many treasures, such as items, recipes and knowledge of the cataclysm which befell the island in ages past, but the most valuable may be a new resource and a sigil of power."
