From the introduction:
Having rescued a young man named Longinus from the grip of darkness, the lightraiders are chased into a cave fortress in the heart of the Gloomy Forest (Sil Belom in the Elder Tongue) by a band of mounted coal orcs. This same dungeon imprisons Featherking the talking eagle, and his companions Archer the white tailed deer and Silvestrano the deer mouse. Master Carthia spoke of their importance in the Rescuer’s plans and tasked the lightraiders with their rescue. Though outwardly it seems the lightraiders have fallen into grave danger, they are exactly where they need to be — in the center of the Rescuer’s will — truly and always the safest place to be.
In the complex, the lightraiders must survive the traps and enemies, free the talking animals, and ultimately confront the dragon lord of the Sil Belom. If they escape, their adventure becomes a heart pounding race to save as many Aladoth as they can before they are killed in the Reckoning, the dragon’s purge. The talking animals assist in presenting the Great Rescue and breaking the chains of guilt in the heart of anyone who will listen.
Once the mission is complete, the lightraiders say their goodbyes and return to Ras Telesar where Master Carthia presents their rewards and offers up the next assignment.
