User blog comment:Alva the Wayfarer/Manscorpion Tark is Black Iron Tarkus/@comment-184.146.107.118-20150326032655

Those helmets are not the same. Tark uses a Roman Centurion style helmet with metallic arm clasps on the side of the face, whereas Black Iron Tarkus uses an English style bucket helm. The armor is diferent too; Tark uses minimal armor that you would see in a gladiatorial arena whereas Tarkus uses armor simillar in style to Centurions. Black Iron Tarkus's shield is a tower shield, which is also Roman, so his armor is somewhat a nod to the Roman occupation of England (given that he has an English helm and the rest of his armor is Roman); Tark's armor is more of a nod to Gladiatorial armor worn by Roman gladiators in battle arenas; the area where you summon him looks simillar to the ground floor (where the gladiators fought) in the Colluseum in Rome.
