After the first 7 days any Dimension is opened, “Dark Rifts” start spawning randomly at entree points every 4-24 hours. NPC combat units come through until the Rift is destroyed by the Player.. These dark rifts continue increasing in power until all of the player controlled units are destroyed and the dimension is close with the World Soul(s) and Interdimensional Heart(s) being destroyed. This mechanism helps to manage the output of Mars and New Paradigm Tokens while requiring players to continue playing and managing the game to continue earning rewards. This is not a set-it-and-forget-it game.
