So I'm attempting to go back and re-read a series I first aquired about 8 years ago but am having a very difficult time finding them. I can't remember the name of any of the books or characters but I WILL write down what I can remember:
The series has a group of "dark knights" that will amputate a limb and then use the bone as a magical weapon. If I remember correctly they also encase themselves within magical armor that allows them the use of their missing limbs. The leader of this group was a prince who fell to 'the dark side'. After a while these knight's bodies start to decay.
There you have it. All I can remember. I hope someone out there can tell me something about the series that will help in tracking it down all these years later.
