That's an interesting one. The Dark Yor achieved enlightement, apparently, and this gave them a bunch of high-end techs. They were willing to give them to me in exchange for the vast stores of relatively junky techs I had, so now I have ships with Black Hole Eruptors and nothing can challenge my power (well, the Dark Yor might have, but I destroyed them before they built any attack ships to worry about). Is that how this event is supposed to work? I suppose this might explain some of those 'Drath magically have HyperWarp III!' reports...
