The Revenge of the Others

The Revenge of the Others is a material dropped only by Dark Gods, and they are useless without killing all twelve, a difficult task for anyone, no matter what gear they may have. If all twelve are combined at Burnt Offering Vat, the smoke will form an eerie reddish shape in the air, which will hover over the player until they go to Olympus and ask Apollo "what this evil is" and "for your help." He will explain that the Others were a legendary species, entirely immortal except several spots and in control of everything, and they cannot be seen by any oracle, only Apollo. (He probably made that last part up) He will explain that to get rid of it, it must be burned away, but he had never done it before and it might not end well.

If it doesn't, the smoke will turn a more sinister shade and fall onto the player. The next time they die, they will see images of Others closing in on Olympus. They will then hear The Gods being tortured and crying for the player's help. "Please! *Player's Name*, we need you! Come to the Nebu--AAAAUUGHH!!!" is one of the most common cries.

If you go to the Nebulism, you will see a large figure appearing as a bright, intricate constellation holding 12 smaller but still large beings glowing and flickering. The Gods are being turned into mortals by the Others!
