About Kemet: The Gates of Thonis, from BoardGameGeek:

Kemet: The Gates of Thonis is a major expansion for Kemet: Blood and Sand that introduces new maps, tiles, and a central game mechanic to deepen the strategic experience. Key Features of the Expansion: Two New Maps: The Renewed Battlefield (6-Player & 3-Player): An updated version of the original Kemet: Blood and Sand map for 6 players, also featuring a foldable 3-God Battle Mode for intense 3-player games. The City of Thonis (2-6 Players): An all-new trading port map centered around an escalating game mechanic. The Crystal Pyramid: A unique feature on the City of Thonis map. A level is added to the crystal structure each round, culminating in a dramatic final round. Controlling the Crystal Pyramid provides the ultimate strategic advantage: the ability to purchase from any colored pyramid board, regardless of a player's current position. New Power Tiles & Miniatures: Heliodore (Yellow) & Hematite (Gray): Two brand-new tile sets, each containing 16 unique Power Tiles plus 3 Game Up tiles and their corresponding exquisite miniatures, adding unprecedented strategic depth. Reworked Classics: The Green tiles from the Book of the Dead expansion are being meticulously reworked and reimagined with entirely new illustrations and refreshed power.
