Nyam is a main character featured in the Crimson Talisman novel. He is a companion to Vaddi and claims to be a humble peddler.
Despite being a peddler he is skilled with a blade. In his defence he claims that being a peddler is dangerous and knowing how to defend yourself is paramount. He was once married to an elf and had two children, all of whom he lost to the Last War. If his son were still alive he'd be of a similar age to Vaddi. Nyam has used many pseudonyms as pointed out by Kalfar who was swindled by Nyam.
