So let’s say in your adventures you help save a race of extra-dimensional beings from being annihilated and, in return, they gift you with a strange ring that doesn’t appear to be wholly in this plane. To give some context, their world is one that responds to thought and emotion much more strongly than our own, to the point that it works almost like a shared dream.
Thing is, nobody is sure what this ring actually does, but everybody who’s magically inspected the thing has stated that it’s a ridiculously powerful and dangerous artifact. So much so that it’s attracting the attention of dangerous enemies.
Any ideas what this thing actually does?
