Etirou.
the founder of Abbadon, he created his own Martial Art style and held himself to a level of honor and morality. and was exiled because of this. Etirou came across an abandoned city, that was in near perfect condition. he recruited many young men and trained them in his new style here. he named the city "Abbadon", because he found that a group of exiled Necromancers built it. he called his new style "Apocalypse", and created the House of Abbadon, which decided which mercenary assignments he accepted. he was feared by many kingdoms after he single-handedly annihilated a two-thousand man army that was attacking a small kingdom near Abbadon. he was nicknamed the "Avatar of Abbadon" for his god-like abilities and skill in battle.
Argoth.
Argoth, son of Daggoth, the Living. Daggoth(of Darkness 2) was the only person to ever go into hell, and come out alive. while he was in hell, he was trained by some of the warriors that had been fighting for thousands of years, he became one of the most powerful and feared men in existance when he escaped. he trained his son in the same way the warriors trained him, the fighting style was systematically named "Netherrealm". and Argoth named the "Demon Slayer" joined Etirou in Abbadon, as a teacher of the new Art, and soon became an Avatar as well. leading an army of only two hundred, he destroyed the entire kingdom of Middlegate for it's ruthless attack of a small defenseless village, without losing a single man.
Ecard.
Prince of the Kingdom of Lusan, he decided he would join the Avatars to gain the respect he needed to inherit the kingdom, rather than his older brother. he however quickly lost interest in Lusan after a few months of training. he quickly learned both Apacalypse and Netherrealm, and in an attempt to gain the respect of Etirou, he mixed them to create his own fighting style. although it wasn't good enough to be compared with the two before it, it did catch the eye of Argoth, who accepted Ecard as his apprentice, and eventually Ecard became good enough of a fighter to earn a position as an Avatar. Ecard later refused the kingdom his father offered him, and remained in Abbadon.
Michael.
after his kingdom and father were buried under the massive rockslide that removed Vultrania from the seventh realm, Michael, son of Twon wandered the earth searching for a purpose, eventually Michael and the group of hunters with him stumbled across the battle lead by Argoth against the kingdom of Middlegate, Michael was in awe. and aproached Argoth asking to be trained. Argoth, having a great respect for Twon, decided to bring Michael to Etirou, who tested Michael and found his potential to be incredible, and his heart to be pure. so Etirou himself trained Michael, and before long Michael had earned a place in the Avatars of Abbadon.
Salem.
Salem's father was a bird-keeper, and he inherited the family business and everything was fine and normal. until his small village was mercilessly attacked and everything he owned was destroyed. he ran to the House of Abbadon to notify them of the evil Middlegate had done. and he watched as his vengeance was exacted. he still felt a sense of loss, and decided to help and make sure no other villages were destroyed for no reason. Argoth found use of Salem's skills, and more importantly, his birds. and decided to train him in the Art of Netherrealm, and quickly gave him the title as Avatar for his saving of many small villages. Salem was trained well, and eventually learned to fight almost as well as the other Avatars.but his hawks were his greatest assets.
Dr. Benuge.
a genius in the world's greatest Academy wrote a book about the science of Magic. a hundred years later a young man at the Academy found the book collecting dust in the Library, foolishly, he skipped the introduction and got straight to the good stuff. even though he had never casted any Magic, it was taking over him. and he noticed. eventually he read the introduction, and learned that he was not only becoming obsessed, but possessed by the Magic he was learning about. and after Amelion Benuge graduated from the Academy. he joined the army of Abbadon to be trained in the Martial Arts so that he would have the discipline to control his Magical obsession. his unique knowledge attracted the attention of the Avatars, and after his training he was recruited. possessing the ability to negate almost any Magical attack, he became a valuable member.
Mistic Rift III
an orphan was discovered by Rift Junior, more or less, Rift saught him out, for he was the only living mortal that could survive casting the fifth element. Rift trained him, and eventually the young man had his name changed. following his sensei, Rift III traveled through several dimensions and times, learning all he can before settling down. unlike his sensei, he has no problem killing anybody. after an impressive light show, with thousands of casualties, Rift III took a place in the Avatars of Abbadon by destroying a huge cult threatening witchcraft on the city of Abbadon. though less than a percentage of the power of Rift II, the third was still one of the most powerful Magi to ever exist. and with Magical powers as great as they were, he trained the new line of Abbadon warriors, the Abbadonian Magi.
Raiden Charles
after hunting the Shakir demon for over a thousand years, Raiden finally got it. Rift II however was not happy with the turn of events, the hate that kept Raiden alive was no longer targetted on the demon, but was rampant, and extremely dangerous. so Rift sent him off the third dimension before he was discovered by the press. and he appeared in the seventh, and almost immediately witnessed a young couple slaughtered by a small demon. it took him less than a second to avenge the couple he had never met, seeing this, Argoth confronted the Ghoul. almost dying a couple seconds after introducing himself, Argoth knew that someone almost as fast as him could become a valuable ally, or a very dangerous enemy. however, Raiden stopped his mindless attack the second he saw a small demon watching the fight. completely forgetting the warrior he was just fighting, he ran after the demon. Argoth read his thoughts and found what was aparrently driving Raiden insane. and twisted his thoughts to fix it. using illusions, Argoth once again focussed Raiden's hate by making the small demon look exactly like Shakir. it didn't even last a second in Raiden's hands. Argoth made another illusion. this time Shakir was too fast, and it escaped. Raiden sensing familiar grounds regained his senses, once again out to kill the demon. Raiden looked at Argoth, and started a conversation. resulting in a deal: Argoth gives Raiden as many Shakirs as he wanted, and Raiden gives Argoth an unkillable ally.
