Ask anyone in Gok-Rock or the surrounding farms and settlements, and they'll tell you that Agusti is a brave kliasta with a heart of gold and a near-unparalleled ship and crew, battling through the debilitating loss of one of his wings and one of his syrinxes to defend the farmers and traders of south Chezri from pirate attacks.
Ask anyone in Kolkuzhn, and you'll be told that Agusti is cunning, but lacks the resolve to do and take what he wants, instead going soft and getting in the way of those seeking true freedom.
All of these are true.
Agusti commands a rag-tag ship of good-hearted people who have no reason to stay on land. With only one voice box left (and without the funds or the interest to buy an artificial syrinx, he can't speak his native kliastan tongue. With his right wing irreparably damaged, he can't fly without the use of at least one adolescent silk wing extension.
Put those factors together, and it's easy to see why the people of south Chezri root for him and his crew; underdogs fighting against the odds to protect people from pirates.
But Agusti only has the skills and the know-how to command his ship without being killed by the multitude of pirates because he once served as one of Bloodscale's Bloodeyes. In fact, he was the first kliasta that worked for her after she died and was reborn as a Revenant.
