Xixinnt

Neither race nor formal organisation unifies this group of squatters whose parents and grandparents were also members of the xixinnit - and so on, as far back as any living member can remember, their ancestors lived on the Shroud in one place or another.

Most squatters are frequently uprooted when some group decides to take over part of the superstructure, driving out all the "vermin" (current residents) to fulfil their aims. The xixinnit have decided they have had enough, claiming that they are descended from those who built various parts of this facility (and some even claiming descent from the original "Builders"), and thus have the right to live where they live.

Seems reasonable enough but, unfortunately, reason doesn't spread across the Shroud as quickly as wealth or violence and the xixinnit soon find themselves resorting to one or the other to protect the rights they believe they have.
