Atanamir does not speak as SA leader.
He never says, "I offer you peace" but "we offer you peace" if you care to read his letters more precisely. 
He always asks for permission from Nightmare, Edvard and Nigel and coordinates before he writes such messages.
You could say he is the press spokesperson of the SA. 
But he is not the leader.
How would the average person realise that the use of "we" meant others were involved in the decision and not a case of someone using the "royal we"
