On the desolate world of Aye, only two civilisations remain - the Novus Aevum of The Spire, and the Havenites of New Haven. Locked at opposite ends of a vast chasm, the two city-states have fought for centuries to rid the world of each other in the name of "peace". But when a carefree Novus scout meets a Havenite engineer, everything begins to change.
