Royalty

Lineage was a big part of Etheria and Naruto Uzumaki was forced into making one of his own. To protect his comrades, his friends, his family, and even people like Shadow Weaver and Hordak. Adora and Catra had a big part in it, too, despite all the pain and trials they'd go through. They were a big part of his 'royalty', in the end.
