Perstault is a centaur fighter serving on his home Island of Fairilund under Captain Jai Rogeddian. He is a calm, thoughtful warrior with unswerving loyalty to Fairilund. He is often found patrolling deep in the jungle serving under Bayonca, whom he is in a quiet relationship with.
Beyonca and the rest of her patrol lead Thean Layisar into the far reaches of Fairilund where they face a new group of coordinated aberrations. Perstault and Bayonca are killed by a giant tunneling aberration.
