I reached my quarters, and just as I did, I took out four dark pink balls and activated formations on them.
Buzz!
They buzzed as the formations on them activated and flew out of my palm before forming a square door. As it appeared, I moved my hand from up to down, and a spatial rift formed inside the door, big enough that I could easily pass through it.
I walked into the rift, and behind me, the rift began closing. As four balls came inside, the rift closed finally without alerting a single system of the fort despite my quarters being one of the most focused areas.
These balls are a much-upgraded version of the balls which I had used before to move around without alerting the sensors or senses of a powerhouse. They barely leave behind any trace at all, and the trace they left behind could be detected by these sensors.
