It dominates the horizon in much of the map, has multiple vendors, and is the headquarters of the Sea Dog faction. If it had a map label, new players might be encouraged to learn more about Arena, or even discover the parkour course. It's a logical meeting spot, and it deserves to be highlighted!
I'm fine with K9 and N13 being unmarked on the map as they're an easter egg and part of the tall tales, respectively. But The Glorious Sea Dog seems far too prominent to be unlabeled.
