Hey, I’ve sketched a little sociogram for a typical raider clan. Think of the leader as the root, his siblings are the first cousins, then each raider’s wife brings in a new branch from another tribe—so you end up with a dense web of cross‑marriages that keeps outsiders out. Wanderers, on the other hand, tend to form a loose clan where each member’s spouse is usually a fellow traveler, so the chart looks more like a circle of equals than a tree. Both setups have cousin‑marriage taboos; in raider groups you’ll see “no first cousin marrying” written in tiny script on a napkin, while wanderers simply avoid any direct kin to keep the circle flexible. It’s like a puzzle—every new member is a new node that rewires the whole network.
