The Kzinti are also part of the Star Fleet Battles gaming universe, are Lyrans and Hydrans also part of the “Cloak Universe”?
No. Although Star Fleet Battles started in 1975, I think of it as a splinter universe and not part of true Trek canon, just an interesting quantum variant, which in many ways is what my version is as well. Again, to be clear, everything in the ST:Cloak universe is based on canon and quasi-canon of the time. That includes as Canon: Star Trek: The Original Series (TOS) “The Making of Star Trek” by Stephen E.
