Unique things to say for each race?

Yeah, I agree with Valk on that bit.

They are named after mythological stuff (places, gods, creatures, heroes, etc), most of it is from norse mythology but the rest is other stuff from greek mythology or other places (I don’t really know which mythology first came with the Phoenix, well, it’s named here Pheonix).

The only excuse I can think of is that since they’re the Rebels of the Empire, they took some of the Imperial Ships with them. I believe the Empire has Greek names.

The Empire seems more Roman than Greek, with the Legion, and Centurion, and stuff.
