The Reptilian Shopkeeper and Beefy Barbarian Shopkeeper sell you items at the Swamp Village Store. The Reptilian Shopkeeper is not a playable character, but it is rumored he is and an unarmored Snakey but you can talk to him in the Swamp Village Store, though he might hiss at you. He does not sell weapons, though the beefy Barbarian Shopkeeper across the room does.
