The Elysium's members turned pale when the gigantic monster emerged from the exploding moon. Half the world was enveloped in all of a sudden darkness.
To kill the Ruvoid God's 3rd form, their master had to borrow the power of nature, earth, and positive energy from tens of millions of prayers. The energy flow and viscosity of the world decreased, and it might take hundreds or thousands of years for it to be replenished.
Their master had obviously killed three Ruvoid God's forms at a heavy price, but there was still the 4th form there!? What if there was a 5th, 6th form, and so on? It would never end, an endless struggle.
Their enemy grew stronger after each death and revival, but their master grew weaker. If this continued, then there would no longer be any hope.
