We were born here, but we're not from here. It's been a millenium since the ancients crossed over into this universe with the nanoswarm in tow, faced the struggles of the Irradiated Zone, and fragmented over that failure. Today, the spiral is full of human life, splintered into cultures embroiled into a long hot-and-cold war — but most of all, it's what the ancients didn't live to see: it's vast, full of habitable space.
This is the spiral. This is where we live.
The schematic shows a sinusoid spiral, seen from the side; it starts from a hollow dot from the left side, grows, and shrinks back on the axis on a dot labeled '৷'. It does so three more times, at dots labeled 'Ⅱ', 'Ⅲ' and 'Ⅳ'. After dot 'Ⅳ', it grows and then starts shrinking again before interrupting.
The growing and shrinking divides the schematic in five parts, between each pair of dots, including the bit after the last dot to the interruption. Each part has different labeled features, and they are, from left to right:
Under the schematic, areas are marked with different colors to indicate different areas of influence:
Direction icons are at the bottom. The direction pointing to the Center is labeled “inward”; the opposite direction, “outward”.
