I like this. It is really more of a campaign idea than a single scenario, since it requires a very specific game world to make it possible. The GM who runs this will need to create said world and have the players encounter both sides, so they can make this campaign altering decision.
It works well if the players are from another sphere, teleported/ travelling here for some reason. Go to Comment
If thieves and murderers are distinguished by their necklaces, wouldn't they just not wear the necklaces? And wear stolen ones (that have been altered to lower the chances of the original owners recognising them)? Go to Comment
It sounds as if the "real" gems are magical and change with the wearer, whereas the fake ones then would actually have to be cut by the gem-cutters. So, you could presume this is known and perhaps, those that can afford it, could have 'alarm systems' at the entrances of their places that search for the proper aura to be projected by a true gem.
To take this thought further, thieves and secret cults could have the same, allowing only those that have certain gems to be able to enter their lairs.
Where do the gems come from initially then? At birth are their destinies intertwined with a gem in some elaborate ritual. Do they always have the same gem as their parents or, depending on the fate of the child, the gem may reveal a vague future? Baby born with a certain gem shows that it will be the future ruler perhaps, or this one is destined to be a tailore etc.
Can use it to introduce the fulfilling of a old legendary poem come to life, a royal embarrassment when the king's son is show to become a simple merchant. Could the worst of the destined thieves be destroyed at birth, or is that something that only happens in life to change the gem?
For destiny's that are unwanted, there could be an entire 'religion' that studies the ruby and has good success changing the future for those parents that can afford it for their offspring. So the future can be changed and the gem change with it, but what point in the person's life will it take to make the new reality come to pass. The cult claims to be able to find the point and use it to direct as the owner wishes.
What if this cult's ways are known by evil ones? What if the cult has their own agenda and kidnaps babies born with the gems and turns them to their own devious agenda? What if, what if, what if? Go to Comment
How would the world react, if a baby is born, and its gem changes to a perfectly round crystal (no edges)? Will it be a messiah? (no edges=lowest class, will serve everyone) Will it be something like an Imperator or a god? (infinite number of edges?) Go to Comment
What is the relation between the gem's magic and the wearer's life force? Whatever, sooner or later someone makes the connection. There will be people reading your fate, healers that feel your problems and can do something through the necklace. Magic can have numerous uses, from detecting still-living soldiers on the battlefield,quickly making diagnosis to easily detecting sneaking people (with necklaces).
Some more serious use: This sounds to be quite a lawful and regulated society. Those rich would pay well for a ritual that would assign a still unborn baby a necklace, its mother carrying it. Not for show, but to know whether it is a son or daughter, or to see if there are any defects. Should the results be not pleasing, it is possible to stop the pregnancy... Whether it is against the law or in sync with it, is your decision. Go to Comment
What if the wearer was so inextricably intertwined with the necklace that if the two were separated, the person would get sick and eventually die? And for that matter, what would happen to the necklaces of people who die? Could lead to some interesting complications for grave robbers. And if like Strolen says, the necklaces reveal the desinty of the wearer, then the ruler will certainly not be pleased if some minor noble (or worse yet, a commoner!) is destined to become the next ruler. So many possibilities... Go to Comment
How had I missed this one? I like it a great deal. It is LifeClocks from Logan's Run plus magical destiny elements. This has so many story and game uses that I am suprised this concept is not more prevolent. Go to Comment
