CURRENT EVENT
CHALLENGE 4: THE HEAD OF CYRUS
This Valentine's Day, Cyrus the Great has proposed to you, the Scythian queen Tomyris. Respond in the only way you know how - with a beheading. Peace is not an option and war is the only way to preserve your unwedded bliss.
Curry favor with the Barbarian Clans of the arid lake to gain an army advantage, but be quick about it - this is going to get messy fast.
