The Unquenchable is a nickname given to a prominent figure from the fire nation. Its meaning is that, unlike their relatives, who quickly lose their strength (just wasting it), become a shadow of their former selves and die, the Unquenchable has not weakened at all. He is considered one of the strongest and oldest representatives of his people. This allowed him to occupy one of the most important places in government and even take control of one of the major cities. But despite his status, he still remains an outcast, especially among the common people. It's all about his way of self-preservation. He is simple — the Unquenchable has moved his fiery soul from an ordinary body to an artificially created one, which he likes to call a "cage". But if only that were okay, his plans are to deprive his bodies and all the rest of the fire people by creating "suitable cages" for them, because only in this way, in his opinion, can they be brought to a better life, where the primitive unbridled flame will be under control.
