The HGC has appeared multiple times, and it's, well, it's kind of obvious. The future analogue of a thousand different empires, compounded into the true nihilism of a time after meaningless tragedy. Sometimes it does good, sometimes it does bad. Every nation state today is a little HGC.

Acronyms are really fun to say. Roll 'HGC' around on your tongue. It sounds real nice, doesn't it? I think it's the 'C' on the end that does it.
