Erik's body has the requisite scars of a soldier. There are a few notable ones, namely one on his left forearm and one over his right eye. The one on his arm was placed on purpose by an old enemy and is shaped like a viper. The one over his eye was given to him by his best friend during a bout of madness. The attack that scared his eye also caused him to lose the eye. So in a way the eye is a "scar" as well as it is a lifelike construct created by a culmination of alchemic research and goldsmith skill.
