I was reading a thread on Reddit the other day where someone was asking about why the Romulans in Next Generation have ridges and I seem to remember that there was a recent-ish novel this and I'm looking for some confirmation. (In case I made this up via mid-stroke.) The way I remember it being explained is that there was a sect or group of Romulans that had come into power during the Next Generation-era that were a variant of the Vulcan-Romulan race who had the ridges. Am I completely making this up or does this appear in one of the novels? And if so, which one? Thanks a bunch!
