This was a dark ring with an appearance of a circle of simple and elegant silver-white patterns.
The material of the ring looked like it was made of black steel, but the surface didn't reflect the unique sheen of metal. Instead, it was more like a matte finish, slightly dark and seemingly specially treated.
Bartlett had once heard from a familiar mage that all Space Rings, if they were to be freely opened and closed with mental power and connected to a Half Plane, must be made with a sufficient amount of Secret Silver during the manufacturing process. As for Bartlett's small leather bag, spatial equipment that required reaching in to take out or put in items, there was no such requirement.
It should be an alloy of black steel and Secret Silver, Bartlett guessed. As for whether it contained other metals, he couldn't know.
Bartlett's attention was drawn to the ring's simple patterns because the pattern style was very familiar to him - Nordic tattoos.
