[@Girlie1Bomba] Good questions!!!

The hollows are basically not a threat at all. Due to the Wind God's attack (and indirect thanks to Elliot) they've all been knocked out or they've scurried back to their nest, so you won't find any on the beach except those sprawled dead or unconscious on the sand.

There's light enough by the clear starry sky -- a wealth of stars and galaxies above! Like there used to be before people made light pollution and smog. xD
