Repressed magic can take many outlets. Some more aggressive routes leave the vessels with scars, blindness, lose of sensation, paralysation and more. While few find themselves decorated in unfamiliar ink. It is believed that those with tattoos have been wrongfully imprisoned, a picture is worth a thousand words and when the vessel can speak their truth no more, the magic within tells the story for them. There is no evidence to prove this as repressed magic is too dangerous to study.
