I think Romulan in Picard S1, and Kwejian in Disco S3 are also not in other books (Kelpian from Disco is in the Disco Campaign Guide). (Romulans only get the NPC-style single paragraph write-up in the core book.)
Are there talents in the CL book at all? I think I read somewhere that the streamlined version of the rules leaves out d6s, so I’m wondering now how much else it leaves out (if that’s correct).
