Gartheia is one of the more secure pirate islands in the south sea. It's shape is similar to an immense flower pot - there are no decent ports or harbors around the circumference of the island as the stone cliffs overhang the waters lower then mast-height. In order to gain access to the higher parts of the island requires similar strategies to scaling a castle wall, with the disadvantages of having to do it from a rocking ship.
The pirates of the island have built, at great difficulty, a set of hoists and derricks to load and unload their ships. There are even plans to build one large enough to lift smaller ships completely out of the water, but these are still just plans.
Once on the upper portion of the island, it appears similar to many other islands in the region, albeit rocky.
The island itself is a massive block of sandstone which is gradually rising from the ocean due to geological forces. The actions of tides and normal waves are eroding the sides of the island as it rises.
See the Hopewell Rocks on Wikipedia. It has an illustration of the idea - the real rocks are much smaller then what I'm putting forth here. Yes this is a shameless plug of my home province.
Even the power of the weakened pantheon was unable to destroy this storm, now termed Nethernimbus by the few survivors, but they were able to direct the storm to an isolated island several days sail west of the devastated Ku! coastline. There the storm was bound by the gods, held in place by a set of powerfully enchanted ward-stones. The storm remains there still - a manifestation of hate and of man's inhumanity to man. None who have approached the island have returned, for the winds have lost none of their power, and these winds have the touch of wraiths!
This island is surrounded by an invisible magical barrier, placed by the gods of a near-dead people, and held up through the handful of priests who still live. The barrier blocks Nethernimbus from escaping, but does not stop the reckless from attempting to land upon it. Only the truely suicidal would try, since the yellow-black raging winds can easily be seen whipping around the island.
Should the remaining priests all meet their end, then this lethal storm of undead power would be unleashed to again bring death to kingdoms! Go to Comment
Such an odd item, though logical in its own way. It falls into the problem of being simply too useful - why would they not make dozens of these with such a useful effect? Anyone with mangled limbs due to accident (or otherwise) would gladly deal with the pain to get back a fully functional limb.
I think the simple adjustment of adding 'realistic' regeneration rates - months as opposed to days, as well as losing significant dexterity, agility and strength as your body restore the nerves and brain connections would help balance it - especially for PC use/abuse.
