The Tyranny of Dragons
Got the worm.
Although it did not know what a dragon was, when told that they looked somewhat like Graoully, but larger, the bird recalled that it had seen a large “dragon” and many smaller “dragon” creatures heading into the raider camp that morning.
Afterwards, the bird scouted the raider camp and informed the party that there were lots of creature moving within the camp and that there were lots of large “lumps” dotted around the camp.
The party later learned that the lumps were huts that the raiders were occupying.
