East of the storeroom is a long series of shops, but only the northern one is occupied. It contains a common provisioner, and the other two have been abandoned.
West of the storeroom is a long building containing a shop and a barracks. The shop is run by Harmon, who sells alchemical ingredients. South of Harmon's shop is the barracks, with Commander Brooks' office. The commander will tell you about the basilisks, but won't ask for your help, and even if you kill all the basilisks you don't get anything from her.
The remaining building, to the south, is a series of apartments. None of them contains much of anything, but you can check them out if you want.
Once you're done with the town, leave to the south if you want to deal with the basilisks.
