Can sense doormaker portals

As I stepped through the door, I fought to keep myself from stiffening.

I could feel the difference in the dimensional frequencies; the world on one side of the door wasn’t the world on the next.

Had someone simply opened a portal in an empty door frame?

There was a pressure differential too.

Neither of the scientists with me seemed to notice anything different; it would make sense that no one knew where the base was if it was on another world, but as far as I knew the PRT didn’t have access to other worlds, and neither did their allies. If they had, there would have been groups out to make a profit off of it, and they’d be less interested in what I was doing.

It had to be a parahuman created effect, or maybe one from one of the evolved. The doorway didn’t taste like any of the doors I’d been through, or any of the portals, which suggested other methods.
