I added the legend bit at the end there.
From what I've gathered about that situation, while the weapon (the soul or consciousness within it) would be treated as a Heroic Spirit, the hero (user) would be summoned as well. If it's like the Fuyuki Holy Grail...the (hero) user would be like Saber's armor???
Or maybe not and it acts like Soul Edge and finds a host.
Wait, CW => NP by themselves. Um...if it's the same situation as the modern weapon, it might just be a Heroic Spirit.
Not your definition at all.
...Are you willfully not reading it?
Crystallized "mysteries". Armaments made using the imagination of humans as their cores and the weapons of Heroic Spirits.
Let's break it down:
"Crystallized 'mysteries'"
Wow, part one of what I used.
Armaments made using the imagination of humans as their cores and the weapons of Heroic Spirits.
Oh my, this might lend credence to your idea...except, wait, what's this annoying little thing called
context?!
And what's this annoying little part right here:
imagination of humans as their cores and the weapons of Heroic Spirits.
Since you brought up the origin of Excalibur, I'll go over the first part in context.
NPs are made using the imagination of humans as their cores, so this means that since Excalibur was created from the wishes of mankind, it must have been an NP at creation, correct?
Wrong.
First off, the imagination of mankind bit of the NP is detailing how regular weapons are attributed NP status. Legends and myths and stories exists within the imagination of the people, from this are the weapons ascended.
It is the ascension process, the exaltation similar to how a hero becomes a Heroic Spirit. It is not about the weapon's creation, it is about the NP promotion.
But I don't suppose you'll accept that, so let me give you an example.
Suppose there is a village (or the world if a village isn't large enough) that wishes for a fan that can bring rain. Suppose the planet decides to make such a fan.
You would immediately subscribe to the belief that the fan would be a NP, wouldn't you?
But now, suppose that the fan is never used, is never known, and in fact not a single story is created about it, there is no legend, it can't even be forgotten since it was never in memory.
How then, can such a fan be a NP? Merely because its creation process involved the integration of an aspect that mankind wished for?
So what?
Suppose that in the ancient past, there was a a monster that ravaged the land. The people, in their desperation, cried out for a weapon powerful enough to defeat this monster. The gods complied, and together they crafted a beautiful bow, and traveling to the deepest depth of the world, forged seven arrows that could pierce even the sun.
Having so created this weapon, the gods casted it down to the world, and chose one person to be the hero who would slay this monster.
Except a trickster stole away this bow and scattered the arrows. The hero, having no bow and no arrows, fiercely fought the monster with the first weapon he could find, a simple branch fallen from a dying tree. In the ensuing battle, lasting over seven years, through rain and sun and wind and snow, wherein the ground shook whenever the hero and the monster clashed, wherein the earth cracked and quake, spewing flames from the bowels of the world, the hero finally emerged victorious but fatally injured.
With the last of his life, the hero hurled the monster into a bottomless chasm, and with the branch, pulled and sealed together the earth. Having finished his task, the hero died where he stood. The branch, welded in the ground, took roots and grew around the hero, marking the grave of the fallen hero.
The people, saddened, joyous, grateful, paid pilgrimage to the hero beneath the tree throughout the ages, singing praises in his name and retelling his tales forever end.
The hero became a Heroic Spirit.
The branch became a Noble Phantasm.
The bow and arrows, were and are not.
The fact that the planet forged it from the wishes of mankind also doesn't make it a Noble Phantasm.
In fact, I noticed that you neglected a certain part here:
People tend to like making powerful Noble Phantasms that don't have anything to do with any legends, mythical weapons, or heroes, but the point of a "Noble Phantasm" as opposed to an ancient artifact is the fact that it has a true name that is used by the original hero to allow for the recreation of its true power. An artifact without any legend or "hero" (in other words, no "true name" or no one able to release the "true name") would just be the equivalent of a powerful artifact, a Conceptual Weapon, or a powerful and old Mystic Code.
Without Arturia, Excalibur would be nothing more than an extremely powerful Mystic Code, and Avalon nothing more than an absolute Conceptual Weapon.
If you think Excalibur and Avalon were NP from the moment of creation, then you are saying that they were NPs before Arturia even gained them. But it was because Arturia used Excalibur, because of her feats and her strength and her legends, because she was remembered, that Excalibur came to be connected to Arturia, that Excalibur came to be linked to Saber,
it is because Arturia used them that Saber is the owner of Excalibur and Avalon, that they became NPs.
The especially funny part here, is suppose that Excalibur and Avalon were NPs before Arturia,
then that runs counter to what you claim, that Excalibur and Avalon required Arturia,
because their existence as NPs would be
independent of Arturia! There are no such requirement that Arturia be the owner, and indeed, if you believe that Excalibur and Avalon were NPs aside from Arturia, there could not have been!
(This is why I especially got pissed when you used those sections from Zero, because it was made exceedingly clear that the restrictions, owner and all that jazz, was the result of Excalibur and Avalon being connected to Saber via the legend of King Arthur. Saying that they were NPs when they were created and saying that they required Arturia was so infuriatingly contradictory by the very meaning of Noble Phantasm that I did not and still cannot see how you would come to that conclusion.)
Now, that's only the first part, the part where you mistook the ideology of creation to be the main aspect of Noble Phantasms.
The second part is section you omitted, Noble Phantasms requires a legend or a hero,
that's the essence of a Noble Phantasm. If the weapon doesn't have a true name, or if it does have a true name
but it has no one who can use its true name, it is not a Noble Phantasm!
Just like how a hero who is not remembered cannot be a Heroic Spirit, weapons that have no legends cannot be Noble Phantasms. Excalibur and Avalon, at the time of their creation, had no hero, and further,
they had no legends. They could not have been Noble Phantasms.
