This reminds me of a tabletop session I had for a game called All Flesh Must Be Eaten. A zombie game set in modern day, much like 7 Days.
One of my buddies was playing a character that SCA/HEMA trained and decided to become a 'Paladin' as a means to deal with his growing
mental health issues in the face of dealing with an actual zombie apocalypse. He made his own chain mail and used his replica sword to
crusade against 'the growing darkness' lol The character also played WAY too much DnD.
