Rings are like mini-wheels and Time is the great leveler, so could be seen as the greatest power. They should call it Wheels of Rings of the Power of Time
As an aside, officially Rings of Power was renewed for 8 episodes for Season 2. It should be noted that Season 2 was ordered before season 1 ever aired, so the idea that Amazon would lower the episode count due to how S1 performed is silly, given that they were filming S2 while S1 was airing, IIRC.
