Hoabna was the ancient figure in the legends of Shaman Village. Living in the world's ancient past, back when Shaman was a larger nation upon Hesperia and back when the nation of Contigo on Atteka down south was part of a larger culture of Jupiter Adepts named the Anemos, Hoabna was something of a national hero and figurehead to the Shamans. The legends remember him as a stoic but very powerful individual.
When the ancient wars of Alchemy were waged during this time period, Hoabna led the nation of Shaman to attack the nation of Anemos, and the Anemos responded by sending their national hero, Yegelos, out to meet him in battle. The two figureheads waged many personal conflicts, one of which was in the location of modern-day Trial Road on Hesperia (and thus was the inspiration of Trial Road's creation), and Hoabna was frankly the stronger of the two. Then some disastrous thing happened to make the fighting cease between the two nations. This event is stated to be connected to the event of putting out the beacons of the four Lighthouses and the subsequent sealing of Alchemy, and may have thus been also connected to the raising of the City of the Anemos to safety in the sky where it would become the Moon.
Following the end of the wars, Hoabna and Yegelos formed a great friendship, along with their respective nations, and to signify this they exchanged national treasures for mutual safekeeping. Yegelos entrusted to Hoabna a magic gemstone named the Hover Jade to Shaman, the Jade being an object laced with the Psynergy-based power of flight that the Anemos were famous for, while Hoabna entrusted a sacred staff named the Shaman's Rod to Contigo. They made a vow to each other: In the future, should a descendant of Yegelos return the rod to Shaman, the bearer will receive the Hover Jade from Hoabna's nation.
The modern-day figurehead of Shaman Village, Moapa, is believed to be directly descended from Hoabna.
