Location of the citadel
The citadel will be placed in the middle (50,50) of the first valley on each of the servers.

Time of the battles
The battles will take place several times a week, and the schedule will be arranged later.

Organizing the battle
Time and distribution of applications for participation
Any member of the Order can submit the application for participation (excluding the current owner of the citadel) by attacking the selected citadel.
If there is an application from someone in the same Order, the applications are combined.
Applications gets sorted by the summarized attack forces of the Orders. The first on the list will be the strongest ones, which then will go into battles by four.
With the beginning of the battle the first four goes into the location, with each order in its own, randomly-chosen, city entrance.
The next four orders from the application will be allowed into the city after 15 minutes.

Actions in the location
Official alliances amongst Orders do not work within the citadel, meaning each order is an enemy to the other. Knights of the same order are, of course, in an alliance amongst themselves.
Walls and gates of the Citadels cannot be passed by any forces but infantry, and moreover, the walls cannot be destroyed.
The four orders goes into the location at the same time, each from their own side.
The first objective of all invaders is to break the citadel gates from their own side to go inside the citadel.
The main objective is to capture the citadel in the center. Time to capture the citadel depends on its level, 2 minutes for each level, maximum level is 10lvl = 20 min.

Capturing and holding the citadel
NPC mercenaries can be hired in the citadel castle, on the gates, or walls.
Hiring 100-500 units right away for mercenary points (alongside the real mercenary points the player has) and artifacts.
Hired units will be bound in tactics to the place they were hired: the castle, gates, or walls.

Bonuses for holding the Citadel
New exclusive mercenary unit (300x the level of citadel castle) will be available for hiring in the obelisks or fountains of Glory for each member of the Order.
For the whole order, there will be 100 000 shared mercenary points.
Artifacts each day for all members of the order.
Other bonuses might be added a little later.

We don't need citadel here at least for next 3-6 months. On old servers citadel is giving almost no advantage for owners. Here for now citadel's artifacts and shared mercerary points will give an unreal advantage for owner

So when is the citadel coming?

i think it would be cool to fight in it and il do anything i can

This looks like a really interesting feature.
When will it be added?

This looks really intresting I hope i can help out with something when I've a big army=D

There are not many orders currently on Camelot. The citadel is a place for orders to fight. Its kinda pointless without there being many orders to fight over it.

I think this server has enough orders to fight in this place and i know the orders that it does have will definitely fight in it. I really hope u guys are thinking of putting this feature in because it looks like a huge part of the game and the server might be lacking without it.

Closed. Support disband an order for no reason so now only two orders left to fight for the citadel, most likely only one order left in the next two weeks, so no point to add this.
