paraselene

There was a long tunnel that ran between Hallalore and Paraselene, if she remembered correctly, and then a shorter tunnel to Estoile Aurore, where Lyardin lived.

The tunnel seemed to last forever - the long road, then, Jian thought, by way of Paraselene - but then the runabout turned out of the main road into a series of smaller tunnels and emerged finally into another pleasant, well-lit district.

A moon dog, moondog, or mock moon, (scientific name paraselene, plural paraselenae, i.e. "beside the moon") is a relatively rare bright circular spot on a lunar halo caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus or cirrostratus clouds.
