I’m working on a reread of Way of Kings right now (I have fully read the whole cosmere; this is my project while I wait for each secret project), and I just got to the part where Shallan’s siblings are talking to her via spanreed about the soulcaster.
Nan Balat mentions that their father’s steward Luesh was found with a pendant with three diamonds in a strange pattern.
Obviously we know from later books that he was a member of the ghostbloods, but according to the coppermind, all ghostbloods must have the symbol tattooed somewhere on their body, so why does Luesh get away with just having a pendant?
One does not preclude the other. That was his ghostbloods keychain. He got it for his 10 year espionage-iversary.
He might have had both, or he might not have been a full member or something
