One day, people who lived at the lower levels of of the World Pillar feared the impending doom that is the dark ocean would consume them, and so they travelled up the world pillar. The people who survived the dangerous journey up the pillar eventually built the city of Eto. Sooner or later, they, or their descendants, discovered Elektricitie and imprisoned her within a crystal inside the Crystal Palace because they felt threatened by her and her power.

At some point, Alua was chosen as the next ruler, after the previous ruler before her died. When a ruler passes, the royalty succession of Eto is chosen through divine revelation by the Senate rather than any royal lineage, and they select from one of the children in Eto to be the next ruler, bringing them back to the castle afterwards. Queen Alua was a special case, however, as she was chosen at an older age, which is usually not how the royal successors are chosen.

During Queen Alua's rule, she had to attend Royal Audiences—a royal hearing event—where, while sitting in her throne, members of the Senate would attend and either entertain her with stories, or discuss economical and political matters, weekly, if not daily. One of the most popular political matters was about the rising dark ocean at the bottom of the world pillar, even though it would not actually reach them for one-thousand years. She even wanted to help the people below the city, by evacuating them to Eto because of the impending threat. Neither the Senate, nor anyone else agreed with her wishes (except for Syd), and it was being proposed that she be disposed of by Xicero.

When Queen Alua was disposed of—having "fallen off" the palace ledge—she was eventually replaced by another or temporary ruler. The only thing that is known about this ruler is that the kingdom was in turmoil under their rule. Sooner or later, Cai ascended to the throne and became King, eventually bringing peace back to Eto, somehow.
