- "Just patrolling. This bridge is an important route. I keep really busy making sure monsters don't nest here by chasing them off the bridge and stuff."
- — Brigo
Brigo has apparently taken it upon himself to defend the Proxim Bridge an important route for travelers from monsters. Despite being equipped with only a Traveler's Spear, he is apparently capable enough of a spearman to defend the bridge from local monsters, keeping them from taking control of it and keeping it safe for travelers. In fact monsters will avoid approaching the bridge or Brigo's camp near the bridge indicating his is more formidable than he appears. In addition to guarding the bridge, he provides directions to travelers, even to places few sane people would go such as the Great Plateau or even Hyrule Castle, though he advises against traveling to either location.
- "Wait a minute! Please, think about what you're doing! I'm young, but you're even younger. I'm trying my best out here, but I get the feeling you're going to end up trying even harder in this world. That's the feeling I get when I look at your face... But maybe I'm nuts. Now calm down and climb off that rail. And don't climb down THAT way. Climb down THIS way!"
- — Brigo talking Link off the edge of the bridge
At night or when it rains, he takes shelter under a covered rest stop where he has made a Campfire that remains lit thanks to being covered. If Link stands on the edge of the bridge or any nearby precipice, Brigo assumes he is going to jump off, and will attempt to talk him off the edge. He will also provide Link with directions to Kakariko Village though only half way as he directs Link to the Dueling Peaks Stable where he can ask further directions.
Given his role in keeping the bridge safe all by himself it is likely that Link as Captain of the Royal Guard and last remaining Knight of Hyrule may have recruited Brigo as he and Princess Zelda worked to rebuild the Hyrulean Army after Ganon's defeat as the army had been all but decimated by the Great Calamity and the Kingdom of Hyrule's army would be in desperate need of valiant souls like him.
