Who is the most powerful being in the Tolkien Universe?
That certainly makes sense. Are there any other beings that come close to Eru Ilúvatar in terms of power?
There are a few beings who are also considered incredibly powerful, such as Morgoth, also known as Melkor, who was the first Dark Lord and a former Vala. Sauron, another Dark Lord, is also considered to be very powerful.
