Gathered Intelligence on this Subject:

Long known as a secretive and secluded culture, the Sphexxian hive colonies of V’zapir have been scattering away from their home as of late. With the preservation of Sphexx culture and livelihood as their motivator, the Sphexxian prison guards of Hvalkatar are a brutally efficient and organized force.

Rapid population growth is increasingly draining V’zapir’s resources. Sphexxian foragers have been sent out to the far reaches of the five rings of Cosmerrium in search of supplies and sustenance for V’zapir. Others, like the guards of Hvalkatar, take up work as a way of accumulating wealth to be shared with their people.
