The Heart of the Planet
However, something sinister happened on all planets... It was discovered that the children of darkness had manipulated the energy cores of the planets, and using their power extracted from the purple matter, they left the planet cores destabilized. But this was only revealed after the sudden explosion of five planets, which, according to geological studies, were not supposed to explode, as they were relatively new worlds in geological terms. So, in order to keep each world safe, constant monitoring and maintenance of the cores are now necessary, where each warlord pays a maintenance fee to prevent the cores from collapsing.
The planet owner will have to refuel the planet's energy core because if the planet's core collapses and explodes, the planet will be automatically put up for sale on the marketplace with a 10% increase in value compared to the last sale price.
