The Lyrisians discover a like-minded species, the Noctians, and merge with them culturally. From this point onward, the cultural term "Lyrisclensian" refers to members of either species. The Noctian homeworld, Nox, had suffered a number of major environmental disasters, leaving the Noctians crippled technologically and severely lacking in shelter. The opportune arrival of the Lyrisians helped the Noctians not only to discover the universe and its wonders, but to end their cultural policy of isolationism that had prevented them from seeking it.
