Vueko

Veko, whose full name is Velo Eluko, is a mysterious "probably human" woman who was chained by her neck in a deep pit of sludge beneath Ilblu before Riko set her free. While in the pit, she spent her time naming, talking to, and singing to the creatures that roamed around her.

History
It seems as though she used to be a delver of some sort, back before Ilblu existed, and had a role in its creation, much like the Three Sages. She opposed the founding of the village, and as a consequence was banished into a dark, sticky pit of mud below where Ilblu sits. It's unknown how long she was there, but it was obviously a long time; her hair had grown many times its original length, her legs are weak from lack of use, and she had not spoken to anybody for ages before Riko found her. She claims that the founding of the village was bad and that Ilblu cursed, and called it "a gathering of curses and children who grow up distorted." Now though, she supposes it isn't so bad a place, since though the narehate that inhabit it are no longer human, they still possess their souls and carry on with their lives.
