...allow me to tell you a story. 

Once, there was a boy. This boy was a brilliant genius. Under the tutelage of another, he fostered his talents at an astounding pace. In the most mundane aspects of the world, he found things to be admired, to be polished and crafted to a mirror sheen.

Innovations that hadn't been dreamed of before. Wondrous things perfect in their simplicity and yet sublime in their function. He created, and created, and created without pause. 

And so, one day, his mentor asked of him: For what purpose do you create? Why do you strive into that frontier to give rise to new things? Why do you examine these systems and tie together the threads that others have missed?

The boy smiled.

[sub]An innocent smile.[/sub]
[b]"Because I want to better the world."[/b]

[sub]A pure smile.[/sub]
[b]"Because I want to be a part of something beautiful."[/b][/center]

Yes, for that boy, it was not for mere invention's sake that he invented. It was for that loftier goal, it was to create a system necessary for human flourishing, it was to pursue the end that laid forwards, that terminus of 'beauty' that his eyes could glimpse. 

And so, his mentor looked upon him, looked upon that smile, and felt one of the same kind blossom at the edge of his lips. He set his hand down on the boy's shoulder, time-worn gaze looking upon him, and spoke.

...and then I pushed that idiot off of the Acropolis. 

Come on! "Because I want to help people"?! "Because it's beautiful"?! How are you going to reach the apex like that?!

THAT'S WHY YOU LOST, KIDDO, TO NONE OTHER THAN-

[color=4ab837]"A single giant hyperpure photonic crystal! 「GREATO」! Do you realize what that means? Even a fist-sized one of sufficient purity can manage the simulation of multiple worlds! If you gain access to its functions, it's undoubtedly a 「GRAND WORLD BREAK」! Ah, wait---!"[/color]

Standing amidst the other gathered Servants, the telltale swirl of magical energy formed in the hand of a raving madman, and condensed into something that even the least competent magus would have scoffed at: Ether Clump. A worthless byproduct created by the lone manifestation of the Fifth Imaginary Element, an 'accident' that arises when one fails at performing magecraft, where the formless void of the Fifth Imaginary Element is not assigned another meaning by which it can gain shape. Indeed, it is useless; its value as a magical reagent is near-nonexistent. It is, in most respects, no different from clay.

However, clay was all that this madman needed. 

His hands whirred to life with a frightening dexterity, molding the clay in his hands as a manic fire glinted in his eyes. The 'presence' he gave off, his radiance as a Heroic Spirit, had been minute at best in the earlier moments, but now it shined brightly.

It took a moment. Energy consumption, material requirements, time requirements, and so on were about as low as they could get. For something as simple as this, something trivial beyond all nature, an inventor of Caster's rank could create it as easily as breathing. 

...perhaps easier, given how he had habits of entering monologues and forgetting to breathe.

Regardless, what looked to be a wooden ruler of the same sort that one could find in the classrooms of the Earth was now in his hand, molded from that 'clay'. The madman squinted at it as he held it up, as if trying to measure something in the air before him. A soft thrum ran through the ruler for a moment in response, before it shattered apart, dissolving into motes of light. Caster seemed utterly unsurprised by this.

[color=4ab837]"As expected! The 「Super Daedalus Spiritron Gauge Mk I」 isn't even able to calculate the full spiritron value energy of the system, and broke merely from attempting it! The total sum of this place, it's probably a level not far from the value of a star! Do you all realize what this means?! We cannot possibly leave this place without adequate preparation- allow me 10[sup]60[/sup] days to prepare suitably! And, moreover-"[/color]

In a single fluid motion, an electric guitar was withdrawn from the guitar case at his side, and was profusely wailed on at random as he turned to face the other Servants. 

As it turned out, he was actually playing pretty well.

Daedalus showed no signs of stopping.
