wow, the people of this place is straight up retards, the insignifisant change the guide dude did was mearly changing the info in the data they had, which wont change the reality itself, and reality is that its the MC's family crest on the ships and the cargo he brought, its like changing the information on wikipedia about ford, making it look like it belongs to some 3rd rate loser and attribute everything ford has done to that 3rd rate loser.
if the lords of the territory is this uninformed about such a major event like thr MC's victory against such a large pirate fleet, itsa miracle they even know their own family name.
