I have a question about Betazoid characters. And since we play a CODA game I thought asking it in here might be the best place to find the proverbial "final answer".
How far back in Trek / Federation history can one go, setting a series, and still have Betazoid PCs ?
I've asked around a lot and found several references on-line. And the answer ranges pretty broadly. From sometime in the 22nd century to only 3-5 years before TNG !
It's pretty easy to find a set-in-stone canonical timeline for other races, like Bajorans.
But when would be the earliest time to see a Betazoid officer in a Starfleet uniform ? Were there Betazoids in Starfleet during the TOS or Movie era ?
And what about Betazoid hybrids ?
When we create characters we tend to focus on a celebrity - a singer or actor - as a sort of basis for the characters' looks. And we also have a little rule - if you want a TOS era character, use an actor who could have realistically acted on TOS (thus our TOS XO is Paul Newman), likewise for movie-era (our Captain is Richard Chamberlain), and so forth.
And we tend to get a lot of characters who "look Betazoid" - basically human with dark eyes. And we are getting more and more TOS era characters with Betazoid background.
So, to the point -
When would be the earliest time to see a Betazoid Starfleet officer ? Or a Betazoid/Human hybrid in a Starfleet uniform ? And what about civilians ? A half-Betazoid, half-Human freighter crewman, in TOS, for example ?
