Korth is a hulking Lizardfolk with deep indigo scales and pale yellow eyes that seem to flicker with static. He wears heavy chain mail that has been treated with animal fat to resist rust, and a tattered crimson cloak marks him as a member of his crew. His shield is made from the shell of a giant sea turtle, charred by lightning strikes.

Korth is clinical and pragmatic, viewing the emotions of mammals as chaotic weather patterns that must be endured. He speaks with a dry, rasping hiss and rarely wastes words. He believes that the 'Crimson Current' is a literal extension of the ocean's hunger, and he finds peace only when the sky is turning black with rain.

Korth was once a tribal elder in the submerged mangrove forests of the south, where he interpreted the will of the storm for his people. When a massive cyclone destroyed his tribe's nesting grounds, Korth did not mourn, instead, he recognized the event as an invitation from the gods of the gale to witness the true power of the sea. He wandered the coasts until he found the 'Crimson Current', a pirate crew that thrived in the very conditions that killed his kin. Onboard, he serves as the Ship's Shaman and Weather-Witch. He uses his mastery over thunder and lightning to mask their approach during raids, ensuring the 'Crimson Current' strikes like a literal bolt from the blue. To him, every ship they sink is an offering, and every life taken is a ripple in the great oceanic cycle that he is destined to serve.
