The Niwrad is the ultimate artifact in the quest for the apparent wasting of time, but the reality is, when complete, it is an artifact of immense power.
If this trinket were to be resting on a workbench, it would appear to be nothing more than an unfinished "ship in a bottle".
When found, the Niwrad is somewhat dissassembled and radiates only the faintest of magical dweomers. It is likely to be completely overlooked as any kind of real treasure if it is simply stumbled upon(this is unlikely to happen, given it’s nature, however).
It should be noted that the ship inside the bottle is of incredibly intricate detail, there are even tiny wood grain patterns engraved on the ship’s wood, to give the appearance of even the wood being small. It must have taken the creator of this item an absolute eon to create this minute masterpiece.
As the ship is re-assembled, at great painfully slow and arduous lengths, the magical aura of the item grows stronger and stronger. At the time of completion, one can almost feel the magical energy that has been stored in the artifact, just by putting your hand near it.
None of the pieces can leave the bottle, making completion of the tiny ship that much more difficult for the worker. However, if the worker spends enough time, he can organize the pieces in such a way that they remain out of the way of actual work until each piece is necessary.
The Niwrad is the brainchild of the late high priest Sari Memak, known affectionately to his followers as "The Patient One", for his almost world renowned lack of patience. He was charged with appeasing the gods with a gift that would be ironic to have received from Sari. He decided to spend the rest of his life creating the most wondrous and annoyingly difficult and time consuming and ultimately pointless trinket that he could come up with, and a ship in a bottle seemed like it fit the bill. Unfortunately, he spent so much time on the details of the tiny ship that he didn’t have time to finish it before he passed away from old age. He had created the keel and decking of the tiny ship, but had not put together the real intricacies before he died of old age. The gods appreciated his gift, and turned the item into an artifact. All of the remaining pieces are inside the bottle, just waiting to be put together.
Whenever the bottle is broken over any thing or person, the magic of the artifact is released.
Depending on the target, the effect varies, but the concept is always the same. Whatever gets struck is reduced to its component parts, whatever those parts may happen to be. Of course, the more powerful the item struck, the more complete the ship must be in order to affect the thing so struck. If the bottle strikes something it cannot fully reduce to parts, it will not break at all; it will seem all but indestructible.
Assuming the ship is assembled enough to work it’s magic, if another magical item is struck, it will cause the magical item to spontaneously revert to it’s state before it was magical, and one can see the process taking place in a compressed timeframe. The process of destruction is VERY rapid, happening over a course of time dependant on the power of the item destroyed, the more powerful the item, the long it takes for the magic of the Niwrad to consume the magic of the item so touched.
If the target is a person, the ship must be assembled quite a bit before it will work it’s magic. At the very least, touching a person with the Niwrad will change their eye color instantly to blue(the eye color of newborn babies). If there is more magic, it will wither limbs, remove knowledge, sap health and strength, and so on, until such time, if there is enough magic, that is to say, if there is enough work done on the ship, to simply reduce a person to little more than a puddle of goo.
If the target is something natural, like a tree or a mountain or something, the item will revert to a state that it was in many years ago. The longer the natural element has existed, the more magic is needed to reduce it to nothingness. As such, while trees require only a little magic to reduce to acorns, a mountain requires a LOT of time to be put in on the model ship to get it’s power to work. It should be noted that even this magic will not simply destroy a land formation, but rather it will modify it to how it was a long time ago. This could mean that the mountain could be fundamentally altered but still exist. This would, of course, depend on the geological history of the area. A volcano, for example, could simply be made dormant, and much of the spread volcanic ash would simply disappear from around it.
The pieces of the ship expand to envelop the item touched, no matter how large the item is. The ship rigging, the portholes, the sails, they all move in a very rapid motion around the item touched, seemingly taking bits of the item and rearranging them in a disorganizing fashion. The swirling mass of tiny ship bits appear to move as a cloud around the item, and one can see bits of the item being discarded as they are removed.
By the end of the process, the ship assembles itself to the least complete possible point, that being that the keel and decking are complete, but nothing else, and the bottle reforms around all of the parts. At this point, the Niwrad may be worked on again, thus imbuing the ship with new disassembling magic.
The exact details of the effects of the Niwrad are left to individual judgement. How long would it take a person to assemble the ship to the point that it could do what they want it to?
