Outside the Universe by Edmond Hamilton

Standing outside the mighty tower of the Council of Suns, with the light of great Canopus brilliant on all about us, Jhul Din, Korus Kan and I watched, days later, as our Andromedan allies bade us farewell. Behind us were grouped the massed thousands of the Council, with its Chief, Serk Haj, beside us, while in close-ranked rows on the ground before us rested the five thousand Andromedan ships that were all that remained of the mighty fleet of a hundred thousand that had come across the void to our universe. From those ships the dozen of the Andromedan leaders were coming toward us, while in them their crews awaited the start.

In the intervening days those crews, those thousands of gaseous Andromedans, had been the recipients of the galaxy's frantic gratitude at having lifted from it the shadow of doom that had hung upon it, in all that time when the serpent-creatures, in the Cancer cluster, had prepared to spread out in their great conquest. Sun had vied with sun, and world with world, to do the Andromedans honor, for they it was, as all in the galaxy knew, who had gathered the mighty fleet that had rushed across the void to our universe's aid. They it was who, with the galaxy's fleet, had smashed the serpent-armada in such a battle as had never been known before. And they it was, too, whose great sun-swinging ships had saved us at the last, had annihilated all the serpent-hordes and their cone of doom.
