Ycthys the Piercing is a servant of the Horror known as The Lord of Pain. The Passion’s Champions encountered him in Parlainth when searching for information on Baxa’s Staff. His long thin claws easily pierced the PCs armor, but it was ultimately defeated.
Ycthys was one of the three “themed” Horrors I made to give the gang a bigger challenge in Parlainth. His theme as a Horror is the fear of needles and the fear all PCs have, of having their armor defeated.
