Lao Ge | Avatar Wiki | Fandom

HistoryPersonalityPhysical DescriptionAppearancesAccording to legends in the Earth Kingdomunderworld, Lao Ge was at least two hundred years old. He himself hinted at being personally acquainted with Guru Shoken, which would have made him more than four thousand years old. Although he held Shokencontroversial ideas in relatively high regard, he also studied the works of Shokenrivals, such as Guru Laghima, and developed his own philosophy. Lao Ge had several disciples during his life, most of whom were only interested in learning about the secret of immortality from him. At some point, he adopted the moniker "Tieguai" and became infamous in the Earth Kingdom for murdering the 40th Earth King. After the Yellow Neck uprisingbroke out in the Earth Kingdom, he passed a village that was completely destroyed by the rebels and discovered that every villager, without distinction to age or gender, had been murdered and had their corpses stacked onto each other. Lao Ge eventually settled on the name "Lao Ge" and assumed the persona o...Get price
