Ranma/Wheel of Time Crossover/Fusion.

[Mitchell]

While no gender changing channellers there are who have had there gender changed. Aran'gar used to be a man before the dark one put her soul back into a female body, and she still touches Saidin.
I think the main problem with having Ranma swear the oaths, is not totally regarding her ageing. While I dont want Ranma to basiclly halve his life expectancy, The three oaths basiclly make him unable to use the One Power like you seemed to describe, to make up for the deteriation of his Ki Abilities.

[Questara]

The Three Oaths are to never speak a lie, never make a weapon for a man to kill another with, to never use the One Power as a weapon, except
against Shadowspawn, to save her own life, or her Warder's, or the life of another sister.

Yeah, exactly how does that third oath work, when we have seen them use the one power against false dragons, againsts saidar wielders, etc. Seems their definition of Shadowspawn must be pretty darn wide... Or is it something else? (I've only read up through about the 6th book, and that was right after it came out, so its been awhile. I was planning on re-reading the series to get a better feel for the story before starting)

[Sailor Sedai (Ellf)]

The third oath is to never use the One Power as a Weapon except against Shadowspawn or in defence of the Aes Sedai's life, the life of a loved one, or the life of a Warder.

Still don't see how that qualifies as not being a violation to use it to still a man who might (okay mostly likely will) go insane in the future.

[Sailor Sedai (Ellf)]

Stilling is not considered using the power as a weapon, because you are causing no physical harm to the man. Sure you are removing his ability to channel, but that doesn't mean you are killing him. (Besides, you can qualify it under Shadowspawn because of the Taint)

[Mitchell]

Actually you are, just not an immediate death. When one looses the ability to channel they give up on life, falling deeper and deepre into despair before dieing.

[Shadell]

Mental alteration. I assume 'weapon' is defined as an immediate physical attack IE: Balefire, not mind altering abilities. Stilling probably doesn't count as a weapon persay despite the fact that it often leads to the death of the stilled.

Consider first that this comes from the perspective of someone who hasn't read much of the novels. Okay, ready?
Now, as a personal opinion, robbing a person of their sense of well-being is worse, and a whole lot messier, than straight-up killing them.
Second, whose definitions do these oaths have to follow?
I mean, I don't like the way that guy across the street is looking at me. He might be a threat to my life. I kill him.
Now, that fits the above psychopath's definition of self-defence, but is a vastly unreasonable decision by any other account. Yet it's permitted under the oaths.
And what definition of 'weapon'? Like I said, stealing a man's sense of joy in life is a lot nastier to me than just stealing the life. So to me, stilling would be a much worse weapon than a knife. And for that matter, mind control or alteration are even nastier, and not even touched on by the oaths. Heck, let's just be blatant: 'I would not hurt thee for all the world, but I'm about to shoot in that general direction and you might do well to get out of the way'.
How about indirect effects? Say, start a fire. I didn't create a weapon, I created a fire. It's not a weapon for a man to kill another with (hell, if we're both female, I could create a fricken nuclear-tipped assault rifle and who could say nay?), but a natural force that may well kill someone, and will with a little creativity.
Or you can still just try to scare the shit out of them with a lot of 'near shots'.
While we're at it, what's a loved one? What if there's a guy across the street who's about to get killed by someone or another? Strictly following the Oaths, I can't do shit, but if I decide I love him, I could do whatever I want.
These 'contractual' loopholes are so easy to toy around with it's not even funny. Just turns the oaths into a joke.

[Mitchell]

You are right, there are a lot of interpretations to the Oaths. As in the saying in Rand Land.
"An Aes Sedai cannot lie, but what you hear from them might not be the truth as they say it" or something. IT basiclly means that the Aes Sedai can switch the truth as they like, with partial truths and such.

[EdenB]

I'll plead ignorance and assume you're right on the timescale and power and withdraw those points. I'll still say it seems complicated, but that's because i've not seen Wheel of Time and from any information i've looked up the world seems fairly detailed. Unlike Ranma, it doesn't seem simple enough to understand even if you've not read it.
Overall i'll just say my opinion on this doesn't count much. ^^;

[Pale Wolf]

"An Aes Sedai cannot lie, but what you hear from them might not be the truth as they say it" or something.

'There are far more effective means of deception than the simple substitution of fact with falsehood'.
It's all dependent on the differing perspectives, different information, specific shades of meaning created by word choice and stressing...
"I didn't kill him", then who did?
"I didn't kill him", then what did you do to him?
"I didn't kill him", who did you kill?
See what I mean? Not one of those statements is a lie, and yet each of them conceals the truth. And I don't even make a study of this.

Severing someone from the One Power, that's Stilling if it concerns men in the Third Age, is not too unlike forcibly seperating a long-time heroin addict from any source of heroin. The subject will fall into a deep depression.
That is the reason all Severings are to be done in the White Tower, to 'help' the subject bear the load.
Also noted on the Red Ajah Amyrlin Seats, by my knowledge there have been atleast 2 complete screw-ups as such, once during the Trolloc Wars, the other instigating the War of a Hundred Years.
Both times due to jealousy did the Amyrlin Seat purposefully at the very least neglect an ally, during the Trolloc Wars it was even worse. Those who have read the Eye of the World will know what I'm talking about when I say Manetheren, Trolloc Wars and betrayal.
Ever since the War of a Hundred Years there has been no Red Amyrlin, 'til Elaida Aes Sedai of the Red Ajah, and those who have read that far know how much of a screw-up she is, letting the Black Ajah* rampage through the Tower and breaking the Tower at the same time.
*The Black Ajah are those Aes Sedai who have repealed their Oaths and serve only the Dark One now, very nasty and lethal. If they were to make themselves public they would be the Dark One's Dreadlords.
Addendum: Wolf, you can trust an Aes Sedai when you ask for asylum, they won't harm you, the moment however they feel you are a threat...
You should also be prepared to pay the price, Aes Sedai are just like the insurance people, you pay a lot, but when you need 'em they ain't coming.

[Mitchell]

Actually in the third age stilling is what severing is called in regards to women. Gentling is what it is called in regards to men.

[Questara]

Yeah, for some reason gentling brings the image of gelding to my mind...

[Pale Wolf]

It is. Spiritual gelding.
