I'm not quite sure what quest you're referring to, but if it's the one you get for checking cell "15" on Pine Island, you need to finish the Pink Dragon quest. To start it, you need to get the guest book in the upper floor of Safen's town hall, then give it to the pink dragon NPC in the same room. Then talk to him at the Western Island beach, in Bangers in the Gloomy Forest, and say he's gay every time. Then you need to unlock his lewd scene in the Shiptown harbor's restrooms. Just keep re-entering until there's a pink "4" above the right stall, then enter the one in the middle. Now you can find him inside cell "15" on Pine Island, and after that, talk to him again upstairs to receive your reward.
If you're looking for Saron, he's in the top left house at the beach, upstairs.
