Frostgrave: Ghost Archipelago (2017)

Description from the publisher:

The Ghost Archipelago has returned. A vast island chain, covered in the ruins of ancient civilizations, the Archipelago appears every few centuries, far out in the southern ocean. At such times, pirates, adventurers, wizards, and legendary heroes all descend upon the islands in the hopes of finding lost treasures and powerful artefacts. A few, drawn by the blood of their ancestors, search for the fabled Crystal Pool, whose waters grant abilities far beyond those of normal men. It is only the bravest, however, who venture into the islands, for they are filled with numerous deadly threats. Cannibal tribes, sorcerous snake-men, and poisonous water-beasts all inhabit the island ruins, guarding their treasure hordes and setting traps for the unwary.

In the wargame Frostgrave: Ghost Archipelago, set in the world of Frostgrave, players take on the role of Heritors, mighty warriors whose ancestors drank from the Crystal Pool. These Heritors lead their small, handpicked teams of spellcasters, rogues, and treasure hunters into the ever-shifting labyrinth of the Ghost Archipelago. Using the same rules system as Frostgrave, this standalone wargame focuses on heroes who draw on the power in their blood to perform nigh-impossible feats of strength and agility. This game also includes thirty spells drawn from five schools of magic, a host of soldier types, challenging scenarios, treasure tables, and a full bestiary of the most common creatures that inhabit the Lost Isles.
