I am real sketchy on the details, asI have never been in a siege battle nor in a guild which controls a city, but here is the little I do know:
- It's a guild feature, not individual
- The guild that "owns" a city collects taxes from all the NPC merchants of the city (maybe of the "region" idk)
- Guild officers can buy scrolls for managing the city's region from the Item Mall. The only scrolls that I know of are:
- One to turn PvP on or off in the "capital" city.
- One to "ban" any player from one of the regional cities controlled by the capital, but not from the capital, itself. Ban is in quotes because while the person is sent to high seas, they can immediately re-enter port.
- They can buy a statue of the guild leader from the Item Mall and erect it in the Capital city port.
- They can buy fortifications to help in the defense of the city.
and that, my friends, is all I know about city seige.
