Finding Sophia

In Lith Harbor, you meet a heavily-bearded crewmember of The Victoria called Teo. He says he has some Weird Medicine but he isn't willing to give it up for free. Instead he says he'll trade it for a sparkling rock. He seems like he knows Maya pretty well, yet he still wants a favor first, knowing how sick Maya is? Creep. Anyway, to get the sparkling rock, you should head to Perion and talk to Sophia, the daughter of the owner of the department store there.
