Pale and hairless trisexual hermaphrodites, one of exch triad bearing young; but that same individual may exist within another triad as a non-bearer. Omnivores of great sensitivity and fragility. Their limbs break easily.
Their very personalities fragment under stress, which seems to serve as a social absolution. It is impolite to recognise a stsho that has changed persona or "Phased" as they themselves call it. Traders. Aesthetes and they do enjoy subtle distinctions in taste and sight.
