A Gathering of Heroes is a prequel, taking place approximately twenty years before the events in The Lost Prince and King Chondos' Ride.
Istvan Divega, a mercenary and famed swordsman, is approached by a mysterious figure with an urgent request for aid.
He joins a band of heroes on a journey to defend the fortress city of Rath Tintallain against a great army that includes sorcerers, goblins, demons and werewolves.
Goblins, demons and worse spill over the Dark Border, attacking Rath Tintallain and the priceless treasure it holds.
The Hasturs fear that the fall of Rath Tintallain will bring utter destruction, and summon a gathering of the greatest heroes-elves, dwarves, and mortal men- for a desperate stand.
