Thomas,
Thanks for replying - are you referring to the "Deep Space Jumps"
sidebar on p171 of GT:IW?

A quick shufti at GT: Rim Of Fire's history chapter doesn't turn up
anything on the relaxation, but 700 years (from ~2300 AD to ~3000 AD) is
a slightly nontrivial period of time and the 2I covered a slightly
nontrivial chunk of space. Especially since the timeline has gone boink
(aforementioned rogue gas dwarf, etc), I'll just have to figure out
which bunch of nutcases (or PCs, but I repeat myself) figure a way
around it.
