Tautine was a location famous for its rings.

In 2369, Q hoped to tempt Amanda Rogers with the possibilities of embracing her origins in the Q Continuum. He told her she could have whatever she wanted instantly, such as precious jewels, works of art, or even walking along the rings of Tautine. Rogers wasn't interested in any of his suggestions.
