The Siege Warfare is the War system between the Guilds from Hostile Kingdoms to achieve the Castle that is authorized to govern the conflict districts.
The castle is surrounded with wooden fence and guard towers at the gates and is composed with a Outer Castle and an Inner Castle each with the gates. The gates of the Outer and Inner Castle are open for the users to enter whereas surrounding gates can only be entered with the Captain of the Guard NPC's permission.

During the War time, all the gates will be closed and the entrance through the Captain of the Guard NPC will be moved near the portal in the Siege Warfare exclusive map.
The Siege Warfare will be accomplished within the exclusive map.
The Siege Warfare will place once a week, either Saturday or Sunday, and will progress from 8 pm to 10 pm for 2 hours. (First Siege Warfare will take place on Saturday and the time can be changed depending on the policy.)

When the Warfare begins for the first time the Castle including village/territory will be Hostile to all the Kingdoms and the first Guild to occupy the Castle will own the territory.
Only the Guilds can participate in the Siege Warfare and the Guild to participate in the Siege Warfare is determined by the sum of total points gained from the RvR that occurred throughout the week (6 days excluding the day of the Warfare).
Independent users can participate through the Mercenary System.
Players can enter the Warfare using Exclusive map transfer NPC located in each occupy territory and the Castle.

If the Attacking Kingdom wins the Warfare, they obtain all the possessed money that Defending Kingdom has saved and acquire all the profits from the Castle for a week.
Defending Kingdom must defend the Castle and achieve victory in order to keep all the profits and redeem the possessed money.

If the defending Kingdom fails to defend the Castle and they have paid high price money for hiring Guards and defense equipment, all the damage from spending lots of money is on the Guild and it could be a deathblow to the management of the Guild.
(50% of all the expense will be redeemed upon the victory of the Defending Kingdom.)
