Vueroeruko

Vueko, whose full name is Vueroeruko, is a mysterious woman who was chained by her neck in a deep pit of sludge beneath Ilblu before Riko set her free.

Vueko, an orphan, who was raised by Juroimoh, a cruel man who physically and verbally abused her continually. He had illusions of grandeur, believing he was "playing the leading part" and that he had been "entrusted" with the Golden City, which he constantly boasted to Vueko.

One day while fishing at sea, Juroimoh and a few fishermen spotted a smoldering, wrecked ship. All that remained of the crew were their mutilated corpses and a single man, barely alive, cowering in the stateroom. This man babbled wildly about a monstrous, man-eating hole and a Golden City at the bottom. Before succumbing to his injuries, the injured sailor gave Juroimoh the Star Compass that points at the location of the Abyss.

As she grew older, Vueko inherited the compass, and trained to be a Delver, so that she could flee her life and find the city herself. As an adult she joined the Ganja suicide corps, led by Wazukyan, whose goal was the same as hers. Despite her lack of self-confidence, she eventually became one of the Ganja's Three Sages. They then followed the compass, reached the Abyss, and started their descent.
