Players use their Kindred Spirits to obtain magical energies on the ether plains. The ether plains is the area where magical energy gathers, collects & can be harvested from. The ether plains vary from game to game, which creates replay-ability. Gain magical energies for each run ascending or descending between 1 & 6. Magical energy can also be obtained from matching numerical of a kinds on the ether plains. Once no further routes exist in the ether plains, players will be able to conclude their final harvest of magical energy. The player with the most magical energy will be crowned the winner. -description from the publisher
