Tyr's magic

tattooed weapons, tools, armor, and equipment that can be summoned at will. once upon a time, the eldest generations of the forgotten realm would tattoo their equipment on their body. however, this could only be performed by one person and the ink was very rare and the one tattooing as the only person that knew where to find the ink. there are some of them left in the world but they are few and far between. there is only one known to you that can still tattoo but you are sworn to never tell anyone who- or what- they are.
