Over a period of several generations and cut off from resupply, the colonists lapse into a primitive lifestyle. By necessity, the azi are allowed to raise families. The non-azi humans are in the minority from the beginning and over time, intermarry with the majority. An Alliance mission first seeks to intervene, then withdraws from direct contact, content to watch as two quasi-feudal, fundamentally opposed societies develop, while a third, smaller group called the "Weirds" becomes much more closely associated with the calibans, living with them rather than the other humans and becoming less comprehensible in the process.
