In the second sentence it should be his parents met
In the third paragraph it should say as zag grew up his father........and put a comma(,)between world and everyone. Also in the last sentence of that paragraph you could put or both,however, he had none at all
In the fourth paragraph, second line, it should be he and his mother. In that same line it should say When he was born until.... and in the next line though is supposed to be thought. In the next line it should say Zags father fought brilliantly but was soon overwhelmed
I'll update this soon
