Shay was unique among the elite of the Falling Stardust. This was because she was a non-elemental being. Her Valdis is attributeless, which means she cannot absorb imperium with distinct affinities.
Xasha later learned from Xandria that these people are called Colorless and are treated as a blessing or curse by the tribe they are born into. Being Colorless means a person who can't cultivate, which is considered a waste of the clan's time and resources. It also means someone who can only absorb and use Pure Imperium. If a clan can afford Imperial Diamonds or not determines the status of blessing or curse.
A Colorless cultivator is a natural Martialist. They are born in a state that one would have to cultivate to Saint Plain to see. Breaking past the limitation of affinities and absorbing Pure Imperium straight from the source.
