Killed hundreds of Knights

"Nicodemus is an ancient foe of the Knights of the Cross," Forthill said quietly. "Our information about him is limited. He has made it a point to find and destroy our archives every other century or so, so we cannot be sure who he is or how long he has been alive. He may even have walked the earth when the Savior was crucified."
"Didn't look a day over five hundred," I mumbled. "How come some Knight hasn't gone and parted his hair for him?"
"They've tried," Forthill said.
"He's gotten away?"
Forthill's eyes and voice stayed steady. "He's killed them. He's killed all of them. More than a hundred Knights. More than a thousand priests, nuns, monks. Three thousand men, women, children. And those are only the ones listed in the pages recovered from the destroyed archives. Only two Knights have ever faced him and survived."
