The characters all have opposite personalities, too. Salamander ≠ Iron Warrior Salmander is kind and emotional Iron warrior is an insecure asshole who's a logical pragmatist (debatable really) Blood angels ≠ Night lord Blood angel openly hostile Night lord is a calm psychopath
It seems yall are not picking up how old the salamander is if he said he used the spoon and fought alongside vulcan in the great crusade and based on his words we can guess this is like mid m30 or m39 and with the ultramarine asking why are there so many spacemarines on the ship
