Barnacle is a small, sun-baked goblin with leathery green skin and a series of white salt-crusted scars across his face. He wears a heavy, double-breasted navy officer's coat that is far too large, causing the sleeves to be rolled up multiple times. Around his neck hangs a tarnished silver sextant and a vial of seawater. His eyes are a striking, pale milky-blue, often darting around as if watching invisible spirits in the air.

Barnacle is a jittery soul who speaks in complex naval metaphors and often refers to himself in the third person as the Navigator. He has a chronic habit of checking the wind direction even when indoors. He is fiercely protective of his spellbook, treating it with more affection than most living beings.

Barnaby Glint was never a typical goblin. While his kin were content raiding caravans in the hills, Barnaby was obsessed with the distant horizon. He stole a tattered spellbook from a beach wreck and taught himself the art of divination, convinced the stars were literal maps to infinite treasure. He eventually became the lead navigator for the Salty Scourge, a pirate junker crewed by a group of rowdy goblins who managed to survive three years as the terror of the Sapphire Coast. Disaster struck during a massive typhoon that locals call the Maw of the Storm. A rogue wave snapped the Scourge in half like a twig. Barnaby watched his crew vanish into the dark water while he was thrown onto a sandbar, saved only by his floating trunk of scrolls. He was the only survivor. He now wanders the dry lands, using his magic to earn enough coin to commission a new vessel, though the simple sound of a rainstorm is often enough to send him into a shivering fit of terror.
