"Hello and welcome to AVATAR: The Celestial Sailors supplemental material! This is the part of the story where we take a little break and focus on an aspect of the world of Avatar that the author felt was unnecessary for the main story-mainly, a brief biography on all the previous Avatars mentioned. As none of these are canonical, this material is meant purely for entertainment and curiosity purposes; also, since it isn't too heavily connected to the main story, you can feel free to skip it if you wish. O-of course, I'd really appreciate it if you read the entire thing...(I am getting paid for this, after all)...b-but don't feel too pressured or anything! Heheheh...heh...heh, hmm.

"Before we get into this, the author has informed me that a warning must be issued, as there may be some objectionable material presented. Also, some entries may be out of order, or contradictory, or even confusing, but the author has stated that he's 'just one guy', and doesn't have an editor other than himself. With that out of the way, here are all the other Avatars mentioned in The Celestial Sailors, in no particular order."

Veruna: the second fire-bender Avatar after Wan. The only thing known about him is that he fought against a spirit called Vasuki.

Nami: the first female Avatar. Nami and her twin brother Nagi held an illicit relationship with one another until Nagi's death. Nami ventured into the Spirit World to save her brother, but failed, presumably because of their taboo. Yami is based on the Japanese creation deity Izanami, although in that tale, she dies, and Izanagi is the one who fails to bring her back.

Vamana: the shortest Avatar, believed to be an air-bender. Vamana saved the world from a dreadful demon when he asked for as much land as he could cover in three strides. Thinking he had little to lose, the demon agreed, only for Vamana to completely circumvent the globe in thee massive jumps, thus reclaiming the world and proving it was round at the same time. Based on the fifth Avatar of Vishnu.

Kurma: a male water-bender who organized the rift that separated the Northern and Southern Water Tribes, though why this was necessary remains unknown. Named after the second Avatar of Vishnu.

Makoto: a male fire-bender Avatar who spent virtually all his life outside the Fire Nation; nothing else is known. Makoto Kino remarks on the coincidence of sharing a name with an Avatar.

Han: an Avatar believed to be an earth-bender who presumably stumbled across the place where Apsu was sealed. Whether or not he was the one who unsealed her is unknown; however, his companions fell victim to the Tears of Apsu, and only he, gifted with the powers of Raava, was able to escape.

Ou P'eng: an air-bender known as "eagle in the clouds", presumably because he could fly. In truth, Ou P'eng invented the gliders that most air-benders use.

Kiyone: the last fire-bender Avatar before Usagi. Kiyone's life was marred with tragedy. She was born princess of the Fire Nation, but once she was revealed to be the Avatar, the royal family designed to use her to their advantage (much like Roku). Knowing that she would be nothing more than a pawn if she remained, Kiyone fled her country with some family and retainers, causing the Fire Nation to declare war on any country that dared give her sanctuary. Kiyone grieved that her actions caused so much needless suffering, but over the years, realized that it would have happened no matter what she did, and in this fashion, she would at least have some independence. Even so, many people still believe that she, along with K'ung Ming, caused the long Age of Strife, although the Fire Nation posthumously venerated her.

K'ung Ming: an air-bender known as "the curly-haired" for his refusal to cut his hair off, and Kiyone's successor. A born rebel, K'ung Ming openly drank, ate meat, and fornicated, usually with other men. He rejected his creed and his status as an Avatar, although he was a fierce proponent of human rights around the world, fighting against slavery, human trafficking, and the then-corrupt justice system. K'ung Ming always said what he thought and felt regardless of the consequences, earning him many enemies but just as many admirers. His contemporaries claimed he was the worst Avatar, but historians look upon his life as one that fought against stagnation and rigidity, affecting the world decades after his passing.

Bitasu: a water-bender from the Swamplands and K'ung Ming's successor, Bitasu (known as Betty-Sue to her people) was a colorful, energetic, passionate woman who put the needs and prosperity of her people (known as "The Crick") ahead of everything else, oftentimes to disastrous results. While she certainly did little to help the world during the Age of Strife, Bitasu nevertheless contributed much to its safety and security. She single-handedly defeated a ferocious reptilian Spirit, wrestled a destructive boar Spirit into submission, and organized her people in a wholesale war against vampiric entities she dubbed "Skeeters". Bitasu despised the highborn and so-called elite, preferring the company of lowbrows, riffraff, drunks, prostitutes of both genders (leading to at least two illegitimate children), beggars, and common laborers, with the exception being the spirit of Avatar Kiyone. Oddly enough, despite being a lifelong illiterate, Bitasu's chronicles are vast and colorful, although all are of questionable legitimacy.

Kalkin: Usagi's predecessor and Bitasu's successor, Kalkin grew up in luxury and abundance, but the Age of Strife ended his bohemian lifestyle. Despite being the Avatar, he was incredibly haughty and selfish during most of his youth, but his titles and riches meant nothing to the young warrior Oboro, who regularly defeated him in combat despite not having any bending powers. Kalkin seemingly changed overnight in a confrontation with the warlord Durga, where he challenged the man's entire army to a thumb-wrestling contest. Despite the overwhelming odds, Kalkin completed his challenge, and Durga, stricken by the Avatar's fortitude and tenacity, withdrew. Kalkin helped stabilize the two Earth Nations during his time and contributed greatly in ending the Age of Strife, but vanished soon after his fifty-second birthday and was not seen again. Many theories still abound concerning his final fate, but as Kalkin himself remains tight-lipped about it, theories they must remain. Named after the tenth Avatar of Vishnu, and based on Siddhartha Gautama.

Sung Chiang: by far the most famous and venerated Avatar at the time of the story, Sung Chiang was a lowly official who nevertheless earned the respect of his contemporaries for his astounding kindness, generosity, and wisdom. After completely reversing a massive drought with his water-bending, people began calling him "the opportune rain". He grew up in the Swamplands, heavily oppressed by the tyrannical Lord Rolando Demys, who was generally regarded as the greatest and most powerful threat to humanity since the demon that Vamana encountered. After accidentally killing his mistress during a heated quarrel, he was forced into a life of banditry. Sung Chiang was not an especially gifted bender, but he was a born leader, and had soon amassed a small but powerful group of bandits to engage in guerrilla warfare against Demys. The exploits of a minor clerk from the marshes opposing Lord Demys spread across the world, inspiring other groups to rally behind him. When it became known that Sung Chiang was the Avatar, he gained even more support, and through many battles, was eventually able to topple Lord Demys and free the land from his grasp. It is said that he died drinking a poison that was meant for his oath-brother. Based on the character from The Water Margin.

Setanta: an ancient Avatar thought to have Fomorii ancestry. He was one of the few Avatars that made direct contact with the Four Lion-Turtles (or at least one of the few they remember), but died young after engaging in a ferocious battle. Setanta is based on the Celtic hero Cuchulainn, whose original name was Setanta.

Xuanzang: an air-bender Avatar who befriended four Fomoriians and journeyed with them to spread Air Nomad teachings across the world, thus forming the first known "Team Avatar". Together they founded three of the four Air Nomad temples, and also made contact with the Lion-Turtles. Xuanzang and his retinue are based on characters from the novel Saiyuki, or Journey to the West.

Almasafir: an earth-bender Avatar, and the first person to use sand-bending. She later taught sand-bending to her people, and became a renowned hero. Her name means "traveler" or "passenger" in Arabic.
