A is for Andonian tea, a favored drink with some admirals at Starfleeet Command in 2364.
B is for Balok. Commander of the First Federation Flagship Fesarius.
C is for Climbing. James T. Kirk enjoyed doing it on some mountains and sheer rockfaces.
D is for Denobulans. I bet the dating scene in highschool is interesting there.
E is for Elas. It was ruled by a Dohlman.
F is for Federation Funny Farm.
G is for Gary Seven. He had nice suits, a talking green cube and seems to have borrowed Dr. Who's sonic screwdriver and copied it at some point.
