Generate an abstract image of a cosmic galaxy swirling in vibrant colors, interspersed with intricate technological structures. The structures should imply a sense of ancient civilizations that once flourished there, with their advanced architectural design in alien styles. Throughout this galaxy, suggestions of epic battles fought among highly advanced extraterrestrial races should be subtly depicted, perhaps through marks of conflict on the structures or dispersed debris in space.
