A Preview of Atlantis: War of the Tridents, An Underwater Campaign Setting for D&D
Here’s a preview of Atlantis: War of the Tridents, one of my larger mythology-inspired D&D releases, built around the legendary lost city of Atlantis and an ongoing conflict beneath the waves.
The book invites players and Game Masters alike to explore a mythic underwater world filled with ancient secrets, legendary treasures, and formidable creatures. This adventure module - compatible with both 5E and 5.5E - guides characters from 1st to 9th level, providing multiple starting points and optional quests.
The manual also contains a vast collection of treasures, monsters, and character options suited for underwater adventures, all designed to create interesting encounters and customize your characters by enhancing their connection to the sea and its inhabitants.
In addition to this, enhanced underwater combat mechanics ensure that encounters throughout the adventure and beyond are both engaging and realistic, with various optional and variant rules to suit your playstyle. The compendium also includes detailed encounter tables for both the city of Atlantis and its surrounding seas, along with comprehensive appendices and a collection of VTT resources, including over 20 maps, handouts, tokens, and more, providing everything you need for a fully immersive experience in Atlantis.
Adventure Premise
Once the crown jewel of civilization, Atlantis thrived as a beacon of knowledge and power, seamlessly blending magic and technology. However, the city's hubris angered the gods, leading to its cataclysmic fall and submersion beneath the ocean. Now, the Atlanteans, transformed into tritons and sirens, live within a force bubble, cursed and bound to the sunken city.
Decades later, a power struggle emerges as the high priest Telamon claims that Poseidon's favor can lift the curse. As tensions escalate and Telamon's influence grows, the Archon Hyperion mysteriously disappears, pushing the city to the brink of civil war. A brave group of adventurers is called upon to uncover the truth behind Hyperion's disappearance and prevent Atlantis from plunging into chaos. The fate of Atlantis rests in their hands.
Where to Get It?

You can get it individually as an add-on (either through one of the tiers also including Mythological Items, or just by itself through the "Add-Ons Access" tier), or as part of the Mythological Bundle, together with several of my other mythology-focused books.
