The main character and focus of "Stormclouds are Thrice Cursed." Quynn is an American Red Squirrel who favors archery, but also collects swords. Quynn is a red squirrel with curious spiraling stripes down his arms and legs and distinctive "sideburns" on his face. Quynn lives in a cabin in the woods outside of Mullock, Utah that he called Stomcloud Lodge. He is a graduate of Mullock High School.

Quynn's family owns the lodge that is one of the major settings of the story. He studies archery and swordplay, despite their archaic nature. He enjoys sparking arguments and twisting words to different contexts. He can be quite brusque at times, and careless with his words. He ultimately wants everyone to get along and be friends and will avoid confrontation whenever possible.

Tan fur with ruddy stripes. One stripe runs from his forehead down his back before splitting in two down his bushy tail. Two other stripes roll from his nose over his ears and under his jaw forming his characteristic sideburns. His back stripe splits at his arms and legs to spiral down them three times before ending in a curlicue on the backs of his hands and tops of his feet. He has large eyes with wide pupils and brown irises. His ears have long tufts of fur extending to a point. His incisors are constantly exposed.

Clothing: Quynn will wear sleeveless or one-sleeved shirts, generally green, and dark blue trousers or shorts. He has hiking boots and climbing cleats for footwear. He will usually be wearing his sword scabbard on his back over his left shoulder and a quiver of arrows over his right. He also will carry a second scabbard with the sword of Martin the Warrior on his hip. He also has a room in his cabin that are replicas of Nightblood, Narsil, a blue and green Shardblade, the sword of William Wallace, The Vorpal Sword, Zar'roc, Rhindon, the Master Sword, Fragarach, and Moralltach. He will switch which swords he wears at regular intervals, but he usually carries the Sword of Martin.
