Margaela's Marble Shop

Found underneath the dried up Oasis is a lair of a Medusa who sells exquisite Marble statues and if you're not careful she will turn you to one. She sells the statues as 1,800gp each and will fight to near-death if the party choose not to buy one or until she turns one to stone and then offers the party member back to them for the heavily discounted rate of 1,500gp.
