Seven Deadly Sins

"Apparently, the Seven Deadly Sins were the strongest and cruelest order of knights in the kingdom, formed by seven brutal criminals who carved symbols of seven beasts into their bodies. Ten years ago, they were accused of plotting to overthrow the kingdom, and disintegrated after all the Holy Kights launched a general offensive against them."
