Huge fan and waiting to catch the next season. Is there and indication in Trek Canon as to whether the royal family still exists within the united earth or did they just fade into history? Something that might be an interesting explore.
Interesting question. Assuming that the royal family managed to survive WW3 (something rather easy to explain away as they have access to god knows how many bunkers and shelters) they may still exist by the time Trek gets to STO's era. Still being figureheads, rather than political leaders, they could still go on, no matter the political landscape of the UK or Earth. Unless all those nuclear bombs during WW3 made the UK turn against the monarchy which is, of course, unconscionable.
