Glashtyn

The Glashtyn are an aquatic species with the body of a human and the head of a horse. Under the rule of the Marquess, the Glashtyn were forced to pull the Barleybroom Ferry, and they would demand a tithe as payment, taking a child from the passengers.

History
The Glashtyn first make an appearance in book 1 when September and A-Through-L are on the Barleybroom Ferry headed to Pandemonium. The ferryman at the time, Charlie Crunchcrab, tries to warn September to hide below deck, but she ignores him, and ends up being dragged out as part of the candidates for the tithe. A Pooka girl was chosen, but September took pity on her and gave up her shadow as replacement.

The shadow was later revealed to have been taken to Fairyland-Below by the Glashtyn, who had hoped she would awaken the Sleeping Prince. But she refused and became queen herself, where she was known as Halloween.

Later, when September came to a village on the shore of the Forgetful Sea, she meets a Glashtyn by the name Oat Knight, who turned out to be the very Glashtyn who cut her shadow away from her. There she discovered that the Glashtyn were not cruel and nasty at all, but actually quite sweet and kindly, only seeming mean because of their enslavement to the Marquess, which ended when she was overthrown by September.
