About a half hour’s walk north of Otari is a sprawling swamp called the Fogfen. The ruined Gauntlight Keep lies within, overgrown with moss and overrun with vermin. The most mysterious feature of Gauntlight Keep is a lighthouse that towers above the ruins, curiously far from the shore. The lighthouse hasn’t ever shone its light in living memory, but there’s nevertheless a vague unease about the structure in Otari—if its eerie light shines, sinister things must be afoot.
