Arcadia: Twilight of the Gods is a sweeping campaign and sourcebook for Dungeons & Dragons 5th Edition that invites players into a mythic world where pantheons of old—Greek, Norse, Egyptian, and Celtic—walk once more among mortals. The age of miracles has returned, but so too have divine rivalries, ancient monsters, and celestial prophecies. In this world, gods contend for dominion not from the heavens but across a reborn Arcadia, a land where mortals may rise to rival divinity itself. Players will journey through living myths, stand before thrones of creation, and decide whether to uphold the balance of faith or tear it down forever. This supplement expands the core 5E experience with divine-scale adventures, mythic character options , and a complete pantheon system for integrating gods directly into your campaign. Within its pages are detailed entries for dozens of deities—each with history, domains, personality, alliances, and rivalries—alongside powerful Deific Orders that bind mortals and immortals in shared cause. It also introduces mythic boons , relics , and god-tier powers that allow characters to ascend beyond mortal limits. From the volcanic forges of Hephaestus to the shadowed underworlds of Hel and Osiris, Arcadia: Twilight of the Gods offers both divine majesty and mortal consequence in every quest. Designed for both storytellers and players, Arcadia: Twilight of the Gods serves as a bridge between mythology and fantasy roleplaying. Game Masters will find rich lore, adventure hooks, and cross-pantheon politics to weave into epic campaigns, while players can embody champions chosen by gods—or forge their own divine destinies. Whether you seek the favor of Zeus, the wisdom of Thoth, or the fury of the Morrigan, Arcadia is a living world shaped by faith, heroism, and hubris. The Twilight of the Gods has begun—will you defend the heavens, or claim them for yourself
