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. Wiraqocha Valley is represented by an adjustable board consisting of 22 hexagonal tiles, each of them being identified by a number from 1 to 12, or a dice combo (pairs or straights). In his turn, each player rolls some six-sided dice, combining them to take possession of territories, or to protect from the opponents the ones he already owns. Every hexagon affords resources or special capacities, which are means to influence die results to fit one’s strategy. There are three ways to win: bring back a huge cargo of Somnium to the Empress; acquire enough scientific knowledge to build the Leviathan, a terrifying weapon serving the Kingdom; or find in the temple depths the four relics that will allow you to reach Wiraqocha’s treasure.
