Absa is a famed engineer and secret martialist of the Elders of the Air Alliance, who live high above the cloudline in the Archai Mountains. Before the Air Armada, winged citizens of the Alliance would fly between the high trees of the Aetherian Forrest and the mountaintops of Archai. The Elders of Air dispensed wisdom and law from the Archaian mountaintops, and Air society flourished under a peaceful neutrality. However, after the Fire Kingdom burnt down the Aetherian Forrest, the winged citizens began to question the peaceful policies of the mountain-dwelling Elders. A rift formed between the Air citizens who could fly and those who could not. Soon the winged Air-dwellers built the Air Armada and declared war on the Fire Nation... leaving the Air Alliance in tatters.
Absa was only a young girl when half of the Air Alliance left with the Armada. However, young Absa, math prodigy and wunderkind inventor, perceived the vulnerability of her mountaintop civilization. She studied the world of Aether and developed a defense to protect the mountains from war. She mastered weather patterns and harnessed the power of lightning to create a permanent electrical storm at the base of the Archai Mountains. This storm barricade has hidden the mountains so well that the Air Elders consider themselves impervious to the turmoil of Aether. Yet, Absa, the inventor of the storms herself, fears that the barricades may prove insufficient. Despite the laws of the Elders, Absa secretly developed her storm techniques for offensive use. In martial arts societies hidden in the caves of the Archai mountains, Absa honed skills that she hoped to never need.
