About a half hour’s walk north of Otari is a sprawling swamp called Fogfen.
Ruined Gauntlight Keep lies within, overgrown with moss and overrun with vermin.
Over the last several generations, hopeful explorers have poked around the
ruins, but they’re generally considered unsafe and wholly picked over today. 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.
