At First, Everything Was Novel

Clue 1/3 for "Nails Hairier than Hair." So, there shall be three clues! They will get progressively easier.

In the world upstairs
Are walls as veils,
Balleting in
Inner winds.

Shadows criss-cross
The songs
That trudge
From throngs
Of masses
Running around,
In chaos
That sneaks over -
Guised in cloaks
That rival its
Counterpart.
