As the man leaves, Jacen begins to try to take apart the double bladed lightsaber with some tool, underestimating the weapon in from of him he soon realizes it's more difficult than he thought. "He was right, these tools are getting me really anywhere. I guess I'll try and use the force to open this, but doubt that'll help me." He puts down the tools, and quickly begins to work on a mold while melting the ingots. "For this I'll probably just use the Beskar, I'll use what he gave me some other time, for an upgrade if need be or for another weapon." Seeing the metal has turned into a liquid, he rushes over and pours it into his mold, developing his beskar hilt. "Ain't no time like the present, time to deconstruct this thing."
Jacen sits down on the bench, placing the lightsaber in front of him, he reaches out his hand, trying to open up the chassis of the lightsaber but has no results. "This is definitely harder than I thought" He crosses his legs as if he was to meditate, he forces his eyes close and thinks hard about opening the saber. Every minute that passes he becomes more and more frustrated and begins to get angered by it. Tightening up his fists, he keeps trying. Finally after almost an hour of trying, the lightsaber lifts off the table slowly but surely, and begins to deconstruct itself, the crystal that comes out has adapted to Jacen and shows a dark black crystal.
Still under intense frustration and rage, he grabs the crystal and unknowingly forces his rage, anger and hate into it causing the kyber crystal to bleed but not change colors. The workshop he's in begins to shake and a burst from the force sends people and objects flying to every corner of the room. He lets out a scream of rage that could possibly send an echo in the force, though he soon calms down returning to a calmer state. He opens his eyes and slowly starts constructing his new blade. After adding the components and crystal he gets up and shouts with excitement. "Finally! After so long, it finally worked, I wasn't expecting it would be this hard though. Time to see how this looks."
He ignites the blade, showing a black blade covered by a crimson red aura. "Not exactly what I was expecting but I'll take it."
Jacen looks around the workshop and sees people staring at him somewhat in a pissed off way, and some of them in shock of what just happen. "Oh no" He thinks to himself worried about what had happened. "I'm probably going to have to explain what happens to the man in charge."
