In Urbion, you are the king of Equilibrion, a city where Incubi (negative dreams) and Sognae (positive dreams) coexist in a delicate balance. Your mission is to maintain this harmony by allocating them to different districts and controlling their powers, all while fending off Chaos entities that thrive on discord. This is a solo or cooperative card game for two players, where you must work together against the game itself. The goal is to claim all twelve City cards before the Dream deck runs out. To do this, you need to balance each City card: the sum of Dream cards played next to it must be exactly zero for you to claim it. Strategy is crucial: play your Dream cards wisely or discard them at the right moment to trigger beneficial effects. But beware of the penalties from Chaos cards! The base game already includes two expansions. The first, "Arch-Squares and Metas," adds new City cards and Metas, which are double-sided (positive and negative) Dream cards, increasing the complexity of your choices. The second, "The Books of Powers," offers more effect options when discarding Dream cards, but at the cost of starting the game with fewer cards in hand. Get ready for a dreamlike challenge of management and balance!
