Intergalactic Transit, The Veins of Ethnis
The Wayhall, the way, the hall, the line, the slip—whatever you wanna call it, it's serene, it's chaos. It's the most beautiful thing I've seen, and sometimes I feel like I am no more closer to understanding it now than I was the first time I rode it. Don't trust anybody who tells you they do understand it, because they're full of shit. There are a million theories, but the damn thing turns over some new detail all the time and breaks all the existing models.
The WayHall is the ever-growing web of WayPoints which define the borders of Ethnis. It links all of the worlds in an intergalactic freeway, allowing for mass transit and commerce. Without it the peoples of Pillar Spoke and Via Lactea would never have met and intergalactic travel may not have happened for thousands of years to come.
Even today experts struggle to understand how WayPoints work.
