Then they waltzed in the air, the long, colourful trails of crystal, golden thread and material starlight that was the tails and tresses of their ball gowns twirling beneath them. Their fellows beneath them on the ground engaged in a complicated waltz of their own, on four legs rather than upright, with wings held at a distance from their bodies. Their own movements were at once differing to and at the same time complimenting the sky-dancing of their peers. The room was filled with music, colour, and the light sound of delighted laughter.
