[@Kho] It only gives a general idea of direction and proximity, but given that Sculptors roam, they can triangulate one another quite easily. Urtelem use this to coordinate their meetings with the fae folk.

Jvan doesn't keep tabs on all Sculpts- she hadn't spoken to Flux in hundreds of years by the time he died- but she's cautious and she'll notice an aberration that isn't masked.

To make chronology work, she's probably been watching Juras without his knowledge until the latest developments with Gadar. Good to keep one's options open.
