I recently read a thread that told the story behind air Asia and why it was made. It doesn't seem like its used as a starting point for noobs anymore just Balamb island is. Any who I was thinking it could be changed into a prison Island or they could just build a new island and put a prison on it like an Alcatraz hence the name Zartacla island. I had 2 ideas for a prison island
1) It wouldn't be an actual prison but an old one, maybe the one the admins used to use too punish ppl when boosting and glitching. But now its run down and a group of bandits use it as an hide out. It would be used as a dungeon and you would receive a quest offer from an npc to go there and reclaim an item or npc like the begging to link to the past. You fight your way through 3 floors of bandit baddies killing a set amount before your able to advance to the next floor, and when you reach the top floor after you clear the baddies a boss bandit would appear then you kill him then receive the key to the room/cell where there is chests containing gralats and the stolen item/kidnapped npc.
Could add a flag on the top and make it a tower for the hat chasers.
2)Its still a prison and if you do something say set up an item in a store and it an steal it you get caught and taken/warped to the prison island (yes you would lose some ap for stealing). When you get to move you talk to an npc convict in your cell to start a prison escape mini game. He tells you of a hidden exit out of the prison and that there will be an npc waiting there to let you out. You would have to find a bush or use rat morph and sneak past guards walking back and forth (I know it wouldn't take much to make npcs mobile). If you get caught you get thrown back in the cell you started in. Then when you make it past you find a hidden tunnel by pushing something out of the way that leads to a npc standing by a pipe who gives you a letter and asks you to deliver it to an npc some where and when you do you get a monetary reward. Then you hop down the pipe Mario style and it comes out by the graal memorial building (the pipe dart is staring into endlessly). There could be player lists for fastest escape time/most prison escapes.
I would suggest making either of these a weekly quest as there is all ready a daily quest and a 12 hour quest atm. You could receive a prison jump suit the first time you do the quest just as an incentive to try the quest at least once.(either the classic black and white stripes or orange).
