A face Makary didn't show yet

"I will have all of them delivered to your place," Makary offered once we finally worked out all the details of the deal. "But I hope I won't hear in the news of some psycho going around killing innocent people with the regulated weaponry…" he added while giving me a long look. 

Makary had no right to know what use I had for those weapons. A portal allowing one to step into another world wasn't something that existed even as a scientific concept, so even if he allowed himself to consider the idea, he would never spare it much thought.

For him, I needed those toys either for self-defense, some sort of distant conflict, or, preferably, an attempt at reverse-engineering all the wonders of human ingenuity hidden in the tech.

The worry that caused this warning was pretty well founded, given the extent of information Makary had.
