Good and Gold (I like the implication Boada's good because Yuvan is an altmer and literally gold)

She does have other senses, but they aren't ones that I think Yuvan's likely to trigger. So Boada will continue down the alleyway until she arrives at a dead end, at which point she starts to shrink. It's quite rapid, she's getting quite a lot smaller very quickly. It'll take under thirty seconds for her to go from a hundred and twenty centimetres all the way down to just sixteen centimetres, at which point she'll walk to a lopsided gutter on the wall leading to the roof, aiming to reach it and clamber up the inside.

She's small now, and stood a bit too far away- her much shorter legs means she's moving a lot slower. Yuvan could probably catch her before she disappears up the gutter and is much harder to follow subtly.
