The Blue Silk River has its headwaters in streams in the
corner mountain range around the aptly-named town of
Vianne Tributaries. These streams are fed through a combination of snowmelt year-round and the monsoon rains around
Rainmaas in the late summer. The Vianne Reservoir at the foot of the corner mountain range features a dam to provide better flood control, as flash floods on the Blue Silk would historically wash away villages that were built too close.
The Blue Silk continues clockwise from the Vianne Reservoir to wind its way almost all the way around Medial A1 - its long, sinuous route goverend primarily by the hilly terrain - before finally flowing towards the commissure at the center of what is now
Silkenvault. Another small reservoir at the edge of the commissure provides Silkenvault with drinking water. Overflows from this reservoir cascade over the edge of the commissure as falls, where the falling water atomizes, evaporates, and returns to the hydrological cycle provided that the weather is warm enough.
During heavy rains or cool weather, some water accumulates in the micro-gravity region of the commissure at Medial A1. Weatherproofed
transit stations and a network of scavenger pumps can keep the commissure navigable in these circumstances. However, if the
Coalition of Breakaway Colonies is making advances in Medial
H and there is a potential threat of air raids against the A side of Silkenvault, the
Grand Army of Voxelia may instead order that the commissure be allowed to fill for a time. Doing so effectively interdicts all air travel through the commissure, but it also helps prevent air raids against the Voxelian heartlands.
I'm liking the hints and allusions to the broader worldbuilding, but don't feel like I need to click on all the links to understand what's being said. All in all, good job! ---------------------------------------------------------------- Feel free to check out my Rivers/Waterways entry: Loch Mesner
