We are in the early XXth century, but the world is not as we know it. In 1895, exploring Amazonia, Auguste Copperpot discovered a gate to a lost valley, occupied by a primitive civilisation. Wiraqocha Valley was the name he gave to this remote Eden. This world enclosed a treasure that was going to revolutionize modern sciences, namely the Somnium, an orange luminescent crystal showing amazing properties. It can be used as fuel, affects matter and even time. Immediately, this virgin land became a new Eldorado for European colonists. Empress Victoria II decided to send several conglomerates to share this promised land and reap the fruits to her benefit. Zeppelin fleet, full of scientists, adventurers and looters, clouded the Atlantic sky.
