They didn’t bother to form the cloud first, wanting to set up the stack of mold and material first. Spike helped hold the mold vertical while rocks were stacked around it to hold it in place. Sand was poured onto the pile to fill in the cracks and offer a base on which the bundle of metal rods was stood, the bottom of the bundle just touching the top of the mold, so it would theoretically pour directly in.
Examining the whole thing, Twilight looked over to the small hole where Rainbow had put her gear, and shook her head.
“You’re moving.”
Immediately, Rainbow crossed her forelegs in a huff.
“I am not.”
“Yes you are! You don’t need to be so close, since the mold should capture the metal. In fact, we won’t even be approaching the pile until several minutes later. You should be over there.”
As she pointed at a rock outcropping a good hundred pony lengths away, Rainbow growled.
“Fine. But I’m going to be watching. No boring hunkering down if I’ve got to be that far away from the action.”
She started moving her things as Twilight checked the pile for the third time, adding a few rocks to steady the rods. Spike brought over some planks of wood that they then put against the sloping side of the pile to keep any of it from shifting.
“Happy?”
Twilight looked back at where Rainbow was, peeking over the distant stones.
“Very!” She replied as she flew over to her.
“So tomorrow, we can make our attempt, try it again. Okay?”
Rainbow pumped her hooves in victory.
“Yes yes yes! I’ll see you then, Twi! I’ve got some things to take care of.”
With that, she zipped off, and Twilight winged her way back home with Spike on her back.
“It’s almost done. Tomorrow we will actually make the sword.”
Silence, and Rainbow shifted slightly in her seat, looking out of the window at the moon, gauging in one look what time it was, the atmosphere’s moisture content, even getting a bit of insight on the winds from the tree tops.
“Come on, I came all this way to let you know what’s up, I’m going to be running on barely any sleep, you can at least let me know if this will work.”
A sigh, and a shape shifting in the darkness of the isolated home, all the lights doused.
“Yeah… Yeah, it’ll work, it’s… Heck, this might be just as good a weapon as the original. You said that it was going to have lightning in it? How is that accomplished?”
Rainbow shrugged, smiling a little.
“Don’t ask me, Doo. I’m not the unicorn. Twilight said that she could make it ‘receptive to atmospheric energy’ during the melting process, I’m guessing that means there’s gonna be lighting in it. But will it work? I don’t want to make you a dud weapon.”
Daring doo leaned forward, the moonlight catching the side of her face and showing her mane a mirror match for Rainbow’s, a bottle of light blue coat dye next to her on the table.
“Yeah. It’ll work, and Dr. Caballeron will think that I’ve really retired, and make his final mistake in underestimating ‘you.’”
Rainbow nodded firmly and bumped hooves with Daring, grinning.
“Just make sure to stay awesome while you’re using my name. If anybody can live up to the legend that is me, I’m sure it’s you.”
