The Shalra were a species that possessed minimal technology, no scientific knowledge and little physical prowess. But their culture consisted largely of intricate songs, linguistic experimentation, and abstract mathematical games.
The Shalra lived mostly in ignorance of the larger galaxy, mostly content with explore the local bounds of their world. That changed when a cosmozoan creature, a harvester, attacked their world to feed on its bio-matter. The Shalra would have been rendered extinct, without the intervention of the Pa'haquel. However even with their aid the Shalra homeworld was devastated, but many of the Shalra were evacuated into their skymounts ensuring the species survival.
