The presence of a large body of water in the Dreamscape answered all questions regarding the Water Nymph's origin. However, it was foolish to assume that she was the only Ethereal dwelling in the depths of the vast open sea.
As Xander looked around, he noticed that most of the islands around him sported quite a significant amount of vegetation. It wasn't just limited to bushes and shrubs, but tall trees and soft-wooded plants as well.
The only exception was the island Xander was currently standing on. Instead of being covered in dense vegetation, this particular island was mostly barren, with a significant portion of it dotted with coarse white sand and craggy gray rocks which littered its shore in little clusters.
Out there in the real world, finding such islands would be perfectly normal, but here in the Dreamscape, every natural formation was a physical manifestation of a person's darkest yearnings and fondest memories.
