Altay: Seafarers Expansion

From BoardGameGeek:

Altay - Seafarers is the first expansion for Altay - Dawn of Civilization, opening the gates to the seas and the mysteries of the ancient Waterfolk. Long forgotten by history, these enigmatic people could command the waves with their songs and bend the ocean to their will. This expansion introduces three major additions. First, a brand-new game board, the Forgotten Sea, where players can establish harbors and expand their civilizations through maritime routes. Second, new rules for shipbuilding, sailing, and naval combat, supported by fresh action cards and technologies such as Shipwrights, Explorers, and Astronomy. Ships allow players to cross sea zones, settle distant lands, and engage in battles across the waves, with unique advantages and tactical depth. Finally, Altay - Seafarers adds a completely new playable faction: the Waterfolk. Through the magic of their wise ones, tied to wavebending and song, they can travel the seas without ships. With their cards, they offer an entirely different playstyle, combining flexibility, resource control, and manipulation of discarded actions. Whether you choose to master the sea with ships or harness the ocean's power with the Waterfolk, Altay - Seafarers expands the world of Altay - Dawn of Civilization with new strategies, challenges, and the thrill of exploration. -description from the publisher
