Rotting Christ - Among two storms

Full moon - raise the rainbow The sea experts - prepare the bow An optical miracle - a moon as big as one Two thunders High strain Threaten the mankind Among two storms It buzzes around your ears An easy day will follow the twilight It must be the last full moon It's near the promised time The thunder bears two mothers The mother bears two sons Echoes in the distance All turn to sun's size It's hot although it's midnight The mothers died at once Father itself the rainbow Both sons will last no more
