I've got an idea stuck in my head about writing up something on Centrum Light, dealing with underlying philosophy and how things actually work there.
First thing is to go over the canonical primary sources, which are:
GURPS Time Travel p 104-106
GURPS Alternate Earths 2 p 109-125 (and the
Federation outtake)
GURPS 4E Campaigns p 541-542, 545-546
GURPS Infinite Worlds p 46-56
And dozens, if not hundreds of minor bits in the Outtime Operations sections of various alternate descriptions.
Am I missing anything?
I'd also welcome thread references to any substantial discussions that won't come up searching here for anything with "Centrum" in the title.
