"Walking in/below starlight" in Sindarin?

Trying to translate that.

I get as far as pad, nu and gilith would work but do not know what modifications would be neccessary.

Also, does anyone know a word for "glide" in Sidarin? Like a boat or a swan on water?

Thank you for any pondering and answering.

Let’s draw inspiration from Dagor-nuin-Giliath “battle under the stars” from the Silmarillion:

Paded nuin giliath
paded nuin giliath
Walking under the stars

Oh my, that is brilliant (no pun intended).

Did not think of it myself but it conveys perfectly what I meant. Thank you.
