ABOUT

This gargantuan creature’s head is round as a ball, but its ears are sharp pointed and have tassels at the ends of them. Its nose is flat and its mouth very wide indeed, but its eyes are blue and gentle in expression. The white, stubby hairs that surrounded its face are not thick, like a beard, but scattered and scraggly. From the head, the long brown body of the sea serpent extends to the horizon. On the back of the body are several fins, which made make creature look more like an eel than a serpent.

Tea serpents are immortal guardians of the seas, patrolling their territory by stretching their long bodies a mile in each direction. They are nigh unkillable and quite powerful, so few dare oppose them. They are largely responsible for peace in the four oceans surrounding Faerie.

The Serpents Three. There are but three sea serpents in all of Faerie, known as Anko, Unko, and Inko. They are benign and quite shy, but not particularly attractive. They are each over twenty thousand years old. Anko rules the eastern ocean, Inko the western, and Unko to the north. The south is managed by a “lesser serpent” that the brothers don’t speak of, but is believed to be managed by serpent golems assigned to babysitting sea fairy children. Once every hundred years, the brothers visit Anko.
