How does the author describe the night?

From the text:

From the dim woods on either bank, Night’s ghostly army, the grey shadows, creep out with noiseless tread to chase away the lingering rear-guard of the light, and pass, with noiseless, unseen feet, above the waving river-grass, and through the sighing rushes; and Night, upon her sombre throne, folds her black wings above the darkening world, and, from her phantom palace, lit by the pale stars, reigns in stillness.
