She and Gem talk for a long time about how to safely search for Ardas. She is an indestructible magic rock who can teleport and can turn off pain, there is not much disastrous that can happen, but the whole reason they are looking for Ardas is that Ardas tend to have problems, and if she shows up while Eru is involved things could get even worse, so it is worth the time invested in precautions.
There are not many places in Arda that are reliably a safe place to land at any point in the timeline. Eventually they settle on trying a teleport to the air just outside Valinor (they considered targeting for Tol Eressëa, but that will miss Ardas where the Elves are still beside Cuivienen), while in the form of a swift.
She tests that if she is adjacent to an Arda this will work, and she tests that if she has no idea whether she is adjacent to an Arda (Gem teleports her somewhere unfamiliar) this will still work.
And she goes to each of the hundred sixteen worlds that have been discovered so far and she tries to teleport to the air just outside Valinor, and when that fails she tries to teleport to the air half a mile above a Bell, because while she is doing this she might as well check for alts.
(She should check for alts of the Noldor too, of course, but she is confident all Bells will react well to learning they are an interdimensional meddling collective of magic-workers and she is less confident about the alts of the Noldor so she only checks for alts of her wife. All non-Arda Finweans so far have cooccurred with a Bell anyway.)
She is in Aurum now. She tries to teleport to the air just outside Valinor. No. She tries to teleport to the air well above a Bell.
