Holy warrior is a name he has been called. One typically thinks of people in shining armor and stuck up chins preaching about how good their diety is. Marcus's faith is different. He has always felt the call to do something but the caller has been without form. Marcus prays to no gods he meditates upon virtue, honor, and goodness then acts accordingly.
Marcus appears in used armor and a tattered cloak. His weapons are old but sharp and well oiled. He has the look of a woodsman more than a knight.
Marcus spends most days hunting for food which he brings to hungry people. When not hunting, he finds himself walking among people. He has a habit of sitting and listening to anybody. He sees the best way to convince another that the virtuous path is best is by living that way; lead by example.
