Legion of the Chimera

Founding
The Legion was started by half-demon twins Isair and Madae. They started the legion to make a safe haven for abominations and to work out a treaty with the Ten Towns to stop any violence between the two groups.

Conflicts Rage Out
On an emmisary mission, representatives from Targos, Bryn Shander, and all the other Ten Towns traveled to the Severed Hand, an ancient elven fortress on the edges of the Fields of Slaughter, the headquarters of the Legion. The mayor of Bryn Shander sent his representaive with finely crafted cakes and pastries, secretly baked with holy water. The representative offers the treats to Isair and Madae, twin brother and sister half-demons, who unknowingly eat the cakes. Of course, the water badly burns the naturally evil creatures throats, and the twins declare war upon the towns. Nothing is known of what happened to the representatives. = The Towns Fight Back = Isair and Madae are furious. They send their hordes of goblins to attack Targos, a major walled town in the region. Targos desperatly sends word to Luskan, promising fortunes and fame. Many mercenaries respond, but many ships are lost.

The Legion Falls
In the game Icewind Dale II, you start out at the ports of Targos, a group of 1-6 mercernaries. You, with the help of the Targos guard, fight back the first initial attack. Eventually, after a trail of events including desecrating a goblin base, killing a half-dragon, getting attacked by skeletons in The Lost Wood, saving Kuldahar from a Yaun-ti invasion, teleporting to Chult and desecrating a Yaun-ti temple, killing an ancient black dragon portal guard, and much more, you find yourself at the Severed Hand and fight off many guards, help out many slaves, and temporarily murder Bane's son, Iyachtu Xvim. You the find yourself in an epic battle with the superpowers Isair and Madae. After a long and gruesome battle, Corellon Larethian's holy water purges the evil that had creeped into the ancient fortress and slowly the fortress crumbles, permanently killing both twins. You luckily survive, and the Legion is no more.
