Hello! So i'm asking for help from any other history buffs who might know something about this but, in my wip novel (Historical Fiction), my main character meets a man (Main character is a Scythian and this man is supposed to be a Sarmatian, living there and all), and gradually notices some things about him that aren't right. The guy is infact a Roman but I need some help on how my guys going to figure this out. The mans been living in Sarmatia for the past 20 something years, so alot of marks or differences might have worn out since then, but for example the Scythian might see some faint marks of a chin strap from the old soldiers Roman helmet? Thanks for taking the time to read this, I hope people have some good ideas!
