An Unexpected Battle

At Camp Half-Blood, Aelita, a relatively new camper, gets premonitions that the camp will be destroyed and everyone will die. She also senses two new presences around the camp. She is approached by one, an elf, who wishes to help her. The other is set on destroying the gods and Earth. Mysteriously three days later, everyone starts dying in camp until only Aelita and one other lives. Then, a huge temple mysteriously forms in the center of camp. An evil ritual is started and it is up to the two remaining survivors to stop the ritual, destroy the temple and evil presence, and to save the gods and Earth. Will they succeed? Or will all life perish on Earth and in the heavens? Dedicated to @AelitaCalypsoZazpi for being my first friend on Wattpad!
