Edhryn Farothran's Lighthouse is an isolated lighthouse on a cape which juts out into the Sea of Ghosts, southeast of Baldrahn. The easiest way to find the lighthouse is to head east from Hla Bulor until the road forks. Head southeast, then east at the next junction and you will soon come to the front door.
Inside it quickly becomes clear how Farothran spends his time: there are two bottles of sujamma and three of mazte and four barrels full of more drink. His only other activity seems to be reading, and copies of Mysterious Akavir and A Less Rude Song are also found inside.
