This is the first full issue of Mage: The Hero Defined.  (Issue 0 is the second of two interludes that take place between The Hero Discovered and The Hero Defined.)
 
Kevin Matchstick and Joe Phat are avatars: reincarnated heroes fighting in the struggle against the forces of darkness.  They have been working with each other for a little while now.  They drive into a town, search out whatever "nasties" they can find, and destroy them.
 
In this issue, they fight a bridge troll, then find a nest of harpies that is using a human hobo for a slave.  They are about to make a plan of attack when Kirby Hero arrives.  In the meantime, a mysterious evil figure called the Pale Incanter has discovered their location.
