Well because noone  knows how to create a faction server or at least the most such as gve server i create a mini guide to help you 
Be sure that you mst spend time and work because i will not give it to you 100% 
First of all faction system was created by Evill33t and for his old server and now the files are stored in his l2jteam "L2JFREE" 
  
Note:The guide was created by EzEraL(John Lamprou) 
  
                Step 1 
  
Go to www.l2jfree.com and brownze the forum to see l2jfree svn and guides of how to complie with maven 
L2jfree is not use ant for complying but maven.In l2jfree forum you will find the guide and support 
  
               Step 2 
  
With eclipse download l2jfree source.When you finish(it will take some time)you will see 3 folders.(Trunk,tags,branches) 
Well interlude version is in trunk folder.So open trunk folder.You will see many other folders but keep in mind that only 2 folders 
consider you.The "Gameserver Int" and "Datapack Int"Then go to gameserver int folder 
  
              Step 3 
  
The faction files are located in:  
1)src\main\java\net\sf\l2j\gameserver\instancemanager.Here you will find  FanctionManager.java and FanctionQuestManager 
  
2)src\main\java\net\sf\l2j\gameserver\model/actor/instance.Here you will find the L2FanctionQuestManagerInstance 
 
3)src\main\java\net\sf\l2j\gameserver\model\entity\faction.Here you will find the  Faction.java the  FactionQuest.java and FactionMember.java 
  
Read these files carefully and you will understand many things of what you must to do! 
  
              Step 4 
  
After you read a bit the java files(faction source)you will understand that you must create some new tables and some htms 
  
Well so now it begins your work.But during the previous guide that many ppl didnt know how to do it i will help little more. 
  
              Sql part 
  
Well you must create 3 new sqls called "faction_quests.sql" "faction_members.sql" "character_faction_quests.sql" 
Be carefull that the sqls must be in the correct sql syntax 
  
             Htm part 
  
Well simply create the followings htms: 
  
start.htm 
already.htm 
switch.htm 
join.htm 
accepted.htm 
noadena.htm 
switched.htm 
declined.htm 
askquit.htm 
story.htm 
quited.htm 
quest.htm 
shop.htm 
wrong.htm 
  
The htm files must be located in data\html\faction 
  
Well thats all.Well if you dont know how to create these sqls and htm files you dont deserve to have a server like this... 
  
  
  
                    FAQ :  
  
What is faction system? 
  
Faction system was created by evil33t for his server.It is like gve but it is not gve.You can choose factions that characters will join and many other things such us faction points and faction war event 
 
  
Is this a gve system? 
  
No but it is the most close for it.It has 3 factions (default good,evil,neutral)and many other things  that related on gve for example the buff coin and you can take a town in your side by winning it 
  
How i can change the faction names because the defaults are neutral,good and evil? 
  
In the file faction.java which is located in "src\main\java\net\sf\l2j\gameserver\model\entity\faction" 
  
Have fun....
