A blade that increases your charisma and political savvy would be very useful indeed, though I imagine that the owner would try to hide the source of his newfound fortune from other potential hosts if he knew. The victim would probably begin to suspect that there was something special about the day he got the blade, and might begin to consider it a lucky talisman of sorts. Those suspicions would only be confirmed when Kingmaker passes on to a new host.
For those reasons, I don't believe that Kingmaker would be very successful in his quest to find more and more powerful hosts. The previous ones would be desperate to get the blade back, and would use what influence they had left to that end. Of course, Kingmaker could hide his appearance at that point so that he won't be recognized, but I'm not sure if that helps.
One question: when you say that Kingmaker changes appearance, do you mean that it physically alters itself into, say, an axe? Or does it use illusion? I ask because you say it tries to make itself appealing to new hosts even while in the possession of another person. Wouldn't the current host notice that his jeweled dagger was suddenly a war axe?
Overall though, an intriguing blade. I'd love to put this into the hands of a PC's most hated rival, then make the player watch as the rival was vaulted to power. This is an interesting series of items, and I hope you continue them.
It's the classic berserking sword; a thumbs up for the back-story.
But really, the idea of a sword fuelling your wrath is so old. If it offered you the choice, again and again, and by making the wrong choice so many times, you'd succumb to wrath... that would be cool.
As EM mentioned, the blade is a nice berserker blade with a backstory. Now, if the sword really fed on rage, its best direction would be to 1. Get its bearer into power, or be acquired by one with power. 2. Induce its bearer to acts which enrage those about him. So long as the bearer has sufficent power, those about him who are enraged may be kept in check, feeding the blade. However, eventually something snaps, the current bearer is overthrown and the blade passes on to a new bearer.
Nice to see one of the sinblades come up! I wonder how someone with an iron discipline would react with this blade. It seems that the wielder would always be walking the line between self-control and all-consuming rage.
I like that you've included a section on the relationship between blades, and look forward to seeing how the oother blades interact with one-another.
The backstory is excellent, and really ties the swords into the setting. However, I'd like to see a bit more about the blades themselves. Some ambiguity is nice for letting a GM weave it into the world, but too much ambiguity makes it harder to integrate them in, because more work has to be done to flesh them out. Also, considering this is a plot, some hooks would also be nice.
This definitely has potential, and I'd like to see it rise to that potential.
I really like the back story, the legend of the blades, however, I agree with Chaosmark, knowing more about the blades, their power, appearance and their temptations would be really interesting, and if the quality of the writeup on the blades is the same as the backstory, you'll be in HoH territory.
Consider approaching a Strolenite whose work you like and propose a collaboration, if you're drying up on ideas/motivation for the blades.
