The Forbidden Islands are an archipelago of islands north-west of Vandura.
The islands are composed of:
Goroma
Goroma is the largest of the Forbidden Islands and is home to a curious Voodoo Cult. The island is dry and hot, with a large volcano being the most distinguishable landmark.
The waters surrounding the island are extremely dangerous and any ship sailing nearby may easily get caught in a storm or tidal wave, and become shipwrecked on this dangerous island.
Traveling from Liberty Bay to Thais one who is at least level 20 may eventually get lost in a tropical storm and become stranded on this island.
If you are shipwrecked, the only way to leave is to collect 30 Wood to repair your ship, but be careful! You might become the next sacrifice of "The Cult", or be murdered by the lost souls of previous shipwrecked crews.
It is advisable to hunt in groups here, to reduce the supply cost.
The deeper part of Goroma is known as Hellgore.
Note: the volcano contains demonic creatures such as Hellfire Fighters, Demons, Diabolic Imps and Dragonlings during the Fire from the Earth Mini World Change. To reach Ramoa it is advisable to wait for the mini world change to end.
Ramoa
Ramoa is the island located in the north-west of Goroma. Ramoa is the second largest island of the Forbidden Islands. The island is covered with dry bush and dead trees and is coated from head to toe with Undead. There are too many bonebeasts to count and a single giant spider near the center. Great caution is suggested. One wrong move and you could be trapped by a dozen undead. Ramoa is the first island you reach through the teleportation chain using the Teleportation Hub. The Teleportation Hub is to the north-east from the hole you come up.
The Giant Spider spawns just a little bit south of the teleportation hub staircase; the Water Elementals spawn further south-west, and can be avoided relatively easily.
Paladins and mages get a really high profit when hunting here, especially if you bring an obsidian knife to skin the bonebeasts. This is not a really good place for knights because every creature in this island has a high melee.
Talahu
Talahu, otherwise known as Hydra Island, is as the alternate name would suggest, crawling with Hydras. Talahu is much smaller than Fibula, yet contains around 20-30 Hydras on its surface making travel on the island very tricky for groups trying to get to Malada and later Kharos. Talahu is a popular destination spot for high level mages seeking fast experience and decent cash. Talahu is also the only island with a mailbox inside the Teleportation Hub. Talahu is the second island in the teleportation chain. Below Talahu one can find a maze of caves with all different Quara scouts and Bog Raiders. Two floors below there is a square maze containing Quara scouts which makes a nice hunting spot for players of level 120 and above. To the north of this maze is a gate of expertise leading to a cave with Serpent Spawns and Medusae.
Malada
Malada is the southern-most island of the Forbidden Islands. Malada is one of only two Forbidden Islands with some form of vegetation. Swamp grass and water litter the island which is home to a large supply of Giant Spiders, Tarantulas, and the various Quara Scouts. Malada is the last island you reach following the teleportation chain in the Teleportation Hub.
If you want to make a lootbag, it is advised to bring a Parcel and a Label to mail it in the Royal Mailbox in the Teleportation Hub. Furthermore a Helmet of the Deep can be brought to block some attacks from Water Elementals. Also don't forget to take one or more of the Killing in the Name of... Quest hunting tasks, if you're going to hunt on Malada.
Under the island of Malada is a series of passages which intertwine in a large underground labyrinth (also famous Quara Hell). These passages are mostly occupied by Quara Scouts, but the occasional Hydra or Water Elemental can be seen.
A hole to the southeast of the island is the only connection to the dreaded island of Kharos where Ferumbras lies in wait in his citadel.
Kharos
Kharos is the smallest, southeast island of the Forbidden Islands located west of Liberty Bay. Many avoid even going near the island, as it is the pinnacle of evil. The evil warlock Ferumbras constructed a tower upon this island, as a citadel. When he was defeated, the mighty sorcerers of the Edron magic guild sealed the entrance to the tower with energy which was impassable for everybody but them. Be wary when the seals here glow bright, for the towers creator might be making his return!
All of the Forbidden Islands are dry and nearly uninhabitable. Many dangerous Creatures thrive here, and some outlaws use these islands to avoid the long arm of Thaian law.
In order to get access to all of these islands you need to do The Shattered Isles Quest.
