Lairo Herreff is a Salsene biologist.
Lairo was chosen to be on the team that explored Kaventro with the Atrenids. Soon enough, he discovered a rather strange object in the middle of a ditch, which turned out to be a strange book. However, he kept this secret from the other team members. He was better recognized for inadvertently dispatching a Terrortooth, effectively saving the lives of perhaps the entire party.
