Towne Basko is an interesting place. There's a Thief who will attack you in the Weapons Ltd Shop, along with two Fighters with hints. One tells you Antos is on X, but you probably knew that if you came all the way here. The other one tells you that with Father Antos's blessing you can earn the Ring. However, you'll have to deal with the Thief one way or another to safely speak with them.
Aside from that, there are a few other items of note. The Guards near the main entrance are fake. You can steal a Frigate and sail it out of town if you have two Keys, though you don't really need one on X.
