From the journal of Ardebast Raconteur:
The Mouse Wing is an organization of brave mice who fly over Pelaria on the backs of birds. They are mostly responsible for patrolling the farming community of Sunnyvale. Given their small size, mice can ride on the backs of birds as they fly over land. Normally, these are Wild birds, but one or two Avian have been spotted amongst the Mouse Wing. Though the Avian are Awakened and capable of independent thought, it still falls to their mouse rider to guide them as Avian are too unpredictable to be counted on on their own. Once they spot danger, the mice of the Mouse Wing will report to the nearest ranger station. The rangers will then deploy to handle the situation. Without the Mouse Wing, the rangers would spend almost all their time patrolling and would often be unavailable should a situation arise when they’re not near.
Excerpt from Zoë of the Mouse Wing:
Most of the birds were of the Wild. They had been tamed by the members of the Wing and lived in symbiosis with them. The mice took care of the birds and in exchange, the birds let the mice ride them. Birds naturally like to fly so it was a good deal. Some birds, like Popkin, were enlightened. They called themselves the Avian and they joined the Mouse Wing for the same reasons the mice did…to help their fellows.
Carja’s Notes:
The Mouse Wing came about as I was thinking about the different groups and organizations that might inhabit Pelaria. It’s not difficult to see that it exists as a direct homage to the excellent comic series, Mouse Guard. Never mind that some birds feed on mice, these are awakened mice we’re talking about.
