Soul-Eaters

The Soul-Eaters, not to be confused with Soul Eater, are a group of seven mages, formerly known as the Healers. One dies in each of the series. 28 years ago as of Wolf Brother, as they grew power-hungry, Torak's father split them up by committing arson. Ahh, arson, my favorite.
The group includes, by order of death:
Wolf Daddy, (the Wolf Mage) thinking his crimes are justified.
Tennis, (the Seal Mage) the crazy ass who wanted to eat Torak's heart out, literally.
Nef, (the Bat Mage) famous for committing suicide by jumping into the demon pile.
Seshru (the Viper Mage), the shrewd, sexy and seductive snake sucker. Apparently Seshru isn't even her real name, sounds a little hissier...
Thiazzi (the Oak Mage), the animal torture... does having a plant for your clan "animal" justify this, that is the question.
Eostra, the Eagle owl mage. With all the power in the world and the Fire Opal, she somehow died in a rock pile but Torak, the scrawny immortal main character invulnerability master, somehow survived.
Narrander the Walker, (the Otter Mage, whose job was taken up by two fucking glowing immortal twin kids) is somehow still alive.
