Tak for Mjøllnir, H., and here´s the next one:

The ring was part of a ransom or blood money, and there was something fishy about the way it came to the mortals. The manufacturer didn´t want to separate from the ring and put a curse on it.

What was the name of the manufacturer, and how was the ring called?

And maybe you know the name of the first and the last ringbearer too?

(mind, we ar not talking about Sauron, Isildur, or Frodo!)
