Rost is incredibly wise and an excellent teacher. However, he will often not answer questions right away, rather guiding Aloy to learn the answer herself, much to her frustration. He is extremely adherent to Nora tradition and honor. Rost has raised Aloy, from cubhood as she was discovered alone in the old ruins. He came to love her dearly and she became the most important figure in his life. He would do anything for her. He is the only parent she's ever known, and the lone influential figure in her life. Despite the general Nora view that old technology is evil, he allows her to keep the technology she finds and tinkers with. He would, without hesitation, give his life to protect her.
