The Island of Destiny was introduced in Update 8.2, it is an island designed as a place for new players to decide and get use to their chosen vocations. Players who have mastered Rookgaard (obtained level 8) can ask The Oracle to visit the Island of Destiny, NPCs await those eager to venture in the mainland, and will give general information on vocations before they decide.
After deciding which vocation suits them best, they gain the Light spell and can enter a vocation-specific dungeon to test their newly acquired vocation. In the dungeons they will also find Equipment to start their mainland adventure off. There is also an everlasting Intense Healing rune on a table in the Druids' house, which is usable by all vocations as often as they want.
Some people throw items on the floor of the isle, you can make lootbags or pick valuable items like Bows, Bear Paws and Wolf Paws that you can sell for good cash when you go to main.
There's really no need to take your armor and weapons from Rookgaard to the Island of Destiny because you receive better armor and weapons once you choose your vocation from the chests in the vocation room. You can sell your armor and weapons before you leave Rookgaard to make extra cash.
If players reach level 9 on the isle, they will get the message "Congratulations to level 9! You should talk to Captain Kurt and head to the mainland now." and all the dungeons will become inaccessible, forcing you to leave the isle. If they choose not to leave, they will receive another message 5 minutes later, "Please leave this dungeon now. Only players below level 9 may hunt here.", If they wait 5 more minutes, they will be teleported out of the dungeon and receive the message "You are ready for the mainland now. Talk to Captain Kurt and choose a city where you'd like to live in.".
PVP (Player Vs. Player) is possible in the Island's dungeons, so watch out!
