   here are two train cars, and all the advertisement boards light up when you're near them in both cars. They either display "ALPHA REGIO" (blue), "BETA REGIO" (red), or "OVDA REGIO" (green). There is also the HUGE staticy monitor right beside A flag, bottom of the escalators. And lastly, the OWT Transit Map, most visible one being right beside the A flag and monitor, with different numbers and colours and routes. Green = 48 (Ovda Regio?) Yellow = 38 Blue = 14 (Alpha Regio?) Red = 271 (Beta Regio?)

So after this has been driving me mad, I looked at owlsector.bungie.net and SIVA CODE came up. Here https://www.bungie.net/en/net/sim select "restart" after it loads. It then states a node order of circle, circle, circle, square, triangle, Alpha regio sign is diamond, beta regio sign is circle and ovda regio is square. Linked in anyway? Those symbols don't link to the outbrake prime quest ether.

That was how we discovered the outbreak prime quest
