On p. 51 a mention is made of a Runelord Ilthyrius, who had the Sword of Sin known as Shin-Tari made. Is this a new runelord who held the position of Runelord of Sloth before Krune?
Yes. Most of the runelords had predecessors (the exceptions being Sorshen and Xanderghul, who were the only runelords of lust and pride, respectively). A few more earlier runelords are also mentioned in the "Runelords of Thassilon" article in Pathfinder #66.
