Return to the wine-dark seas of Theros with Odyssey Anthology Volume II: At Thassa's Mercy. Taking inspiration from the Odyssey and other Greek myths and Greek-myth-inspired media, the Odyssey Anthology provides everything an adventure will need to plot a course across the Theran seas like the legendary seafarer Callaphe, upon oceans dotted with islands rife with myth and mystery, each with their own adventures.
Included in Volume II are rules for appeasing and angering the gods, expanding the piety system to include rules for religious rites like animal sacrifice, votive offering, libations, and mystery rites, as well as rules for the anger of:
- Thassa, God of the Sea, whose rage is characterised by turning the sea and the monsters within it against those who anger her.
- Athreos, God of Passage , whose subtle condemnation brings characters closer to the underworld.
- Keranos, God of Storms, whose wrath comes wreathed in lightning, under dark, rumbling clouds.
10 island adventures:
- Arinos, The Coral Throne by Darren Kenny - A pillar of rock floats in the air above the Theran ocean, adorned with a ruined temple of Phenax, God of Deception. Ascending the rocky climb leads to further mystery, the island's ruins hinting at more to it than meets the eye - water-filled cavern system, home to one of Phenax's ardent followers: the Coral Queen.
- Minuvos, the Ashen Vineyard by Frederic Walker (Kor-Artificer) - A volcanic island rich in fertile soil and vineyards, which produces some of the finest wine on Theros, but the excessive, luxurious lives of the island's rich landowners have been disrupted by an ash-wreathed haunting, soon to be joined by other consequences of their greed, callousness and cruelty the last time the island erupted...
- Armonía, The Isle of Eternal Harmony by Michael Haney - An island where mortals live in harmony with the Returned, gold-masked undead escapees from Theros's underworld. While the Returned live peacefully, filling the same roles as farmers, fishers, craftspeople and merchants that they had in life, a threat looms over this island's harmony - an agent of one of the gods, who seeks to bring the Returned back to their rightful place in the Underworld.
- Cynyrea, Isle of Miasma and Monsters by Jesse Byrd - River channels, hot spring and caverns dot the lush and swampy landscape of Cynyrea, making the foggy island an ideal habitat for many of Theros's monstrous creatures. Unbeknownst to the folk of Zantharos, the island's polis, the fog obscuring the island's coast is not natural, and tracing its source to inland ruins half-submerged in the swamps reveals a terrible threat to the island.
- Karpea, Spire of the Oracle by Green Bird RPGs - An enraged Thassa imprisoned her former lover, the human oracle Teis, on this storm-wreathed spire of stone. Far-seeing Teis, blessed by Kruphix will still provide her oracular wisdom to those who visit her, though they must navigate the raging storms, survive the island's giant crabs, and solve the riddle of Teis' guardian to have any hope of meeting the oracle.
- Laegros, Cannibal Arena by David Berg - Content Warning: Cannibalism, drugged food to induce unconsciousness. - The small population of farmers who dwell on the rocky island of Laegros have been brought under the iron fist of a small cult of cannibalistic worshipers of Kroxa, Titan of Eternal Hunger. The cult's leader, Anastaeus, delights in having visitors to the island, inviting them in to dine with him then forcing them to face him in the arena - a dreadful challenge, for as long as he touches the ground, he is touched by a portion of the titan's monstrous power.
- Larynthia, Oracular Conclave by Sven Truckenbrodt - A lauded oracle of Thassa dwells on Larynthia, surrounded by three bands of followers, each with their own ideas of how to best honour her wisdom. To reach the oracle, characters must impress each faction through debate, revelry and stargazing.
- Memnos, Island of Slaughter by Jayme Craig - Tension has been mounting for years between the two cities of Memnos - the Heliod-blessed polis of Arctosia, and the Erebos-following city of Mesembra. But as the characters arrive, tensions boil over, with the disappearance of Helen, princess of Arctosia, assumed by her father to have been kidnapped by Mesembra. But all may not be as it seems, with Mogis casting his bloodthirsty gaze over the island, eager to enjoy the impending slaughter that his followers seek to bring.
- Ifaísteius, Island of Creation by Richard Jeter - The fervent craftspeople of the volcanic isle Ifaísteius devote their lives to creating masterworks worthy of their patron god Purphoros, God of the Forge. If characters visiting the island intend to leave freely, they too must create a masterpiece, or aid a poet in writing a new epic.
- Khelosari, Eelbrood's Prison by Zeke Gonzalez - A well-known myth speaks of Khelos, a mortal who stole Thassa's bident to bend the sea to his will, only for the sea god to take her revenge by transforming Khelos's family into eels. The truth behind the myth is out in the Theran sea, where a strange upturned island hangs from chains above the ocean, home to strange human-eel hybrids, and Khelos himself, who also underwent his own transformation...
Also included are rules for NPCs and monsters, including new foes like the skeletal sentry of the underworld, the bloodthirsty Marauder of Mogis, and the colossal Khelos.
