The hero Hawkslayer is a recurring NPC that the party can have join their ranks to aid their quest in hunting down Tarjan. They first come across him when they arrive in Arboria, and again in Kinestia. In the last dimension, Malefia, the characters find his dead body.
There are many references to Hawkslayer throughout the early dimensions. The Old Man mentions that he has sent him ahead of the party on his own to help track Tarjan's movements.
