About the game

What you do in a play session

If you're already a fan of Cloudspire, get ready to dive into the darkness with the Keel expansion. Here, the strategy revolves around one core concept: spire manipulation. For the Keel faction, spires aren't just landmarks on the map; they are the very source of their power. Representing void-based technology, these spires are the only way for Keel units to transform into their promoted versions, turning them into devastating war machines. But beware: this power is volatile. If your minion leaves the island hex containing the spire, it immediately reverts to its non-promoted state. In short, maintaining a firm grip on the Source wells is essential for survival and dominance.

Beyond the spire mechanics, the expansion introduces heroes that completely shift the game's dynamics. There's Chira, who can boost the faction's Command Points (CP), and General Eko, who is so imposing that he functions as a spire himself. A special mention goes to Chira's 'Poise' ability, which allows you to increase or decrease your minions' movement stats. This opens up an incredible strategic range, letting you hold your forces back for a coordinated strike or accelerate your advance to secure victory before the enemy even realizes what happened. It's the perfect expansion for those looking to add a layer of tactical complexity and dynamic heroes to the conflict of Ankar.
