The Archipelago, as it has come to be called, is unlike anything you have encountered before. While fragment rock is everywhere in the Broken World, such a strong concentration, and in such a permanent arrangement, is unheard of.
Fragments in the archipelago are large by the standards of the Broken World. A day's walk across, most can accomodate several villages as well as a number of natural features, such as hills, forests, swamps or barren plains.
A few of the fragments have a much more… interesting topography however. Once your settlement is established, these would be worth exploring.
Never before has regularly moving between fragments been an option. An ancient network of structures allows bridges, ropes and ladders to be set up and taken down as the fragments approach each other. These are old and probably unsuitable for more than a lone person at a time.
Due to the size of the Archipelago, travel between fragments is lengthy, on foot for those without beasts of burden, or if crossing onto another fragment. Animals tend not to like being suspended above the void.
Also, the constant shifting and weaving of the lands of the Archipelago make getting from A to B a nightmare, particularly when they've gone via C, which now seems to be heading in the wrong bloody direction. As yet, no-one has managed to chart the interactions of the fragments.
Most fragments appear at a glance to be verdant, but devoid of civilization. The howl of wolves tell you that bestial life is plentiful enough, and that in itself may be a problem for an unprepared clan.
Here and there, however, are telltale signs of others. Clansmen have come back with less-than-ancient tools, or discarded clothing. Occasionally you have seen plumes of smoke from the forests of fragments you thought were unoccupied.
And then there are the ruins. Someone must have built the bridge points for a start, remains of much more ancient structures keep turning up in the fields you till. Other clans talk of more complete ruins, but as yet no one has found time to explore.
