The door opened. And shortly after closed.
Kahlil said nothing as Demiurge brought in the equipment and items he would need for the task he'd set himself. Breaking a Solari crystal. Part of him regretted suggesting it in the first place, now that he realized he'd be locked within this room. The items given would help, sure, but what he needed.. No, this would have to do. His memory of his childhood wasn't gone, after all.
And old habits weren't so easily forgotten.
The first step was a basin. All alchemy needed a foundation. With nothing else to do for the next week otherwise he set to work. Focused on it. Dove back into the darkness he'd left behind. Just hate alone wasn't going to do what was needed. Study. Knowledge. Old tomes were scattered through the room for ease of reference. Blood was spilt, his own, though he knew he'd need more to complete the basin. Enough to get it started.
By the end of the second day he'd have the basin ready for the first drop. A simple knife carved open his palm as he let his blood fill the runic carved bowl. He didn't even flinch as his skin was split. Time wasn't a luxury. He barely had enough time to test his theory, let alone rethink it if things went poorly. He clenched his fist once enough had dripped in, stopping the blood flow. Then, lightning. The purest manifestation outside Sorcery of the Dark Side was unleashed onto his blood. It bubbled and gurgled as the runes flashed and brightened.
First step complete. Onto the next.
By the end of the week the room he was trapped in was.. Ruined. Scorch marks of lightning signified his moments of raw anger. Hastily drawn runes and mathematical equations sprawled out underneath or over the blackened steel. Papers were scattered. The basin in the center glowed an unnatural red from the energy he'd poured into it. Bandages covered his arms, fingers, from where lightning had burned flesh and blade cut skin. He let himself focus on only the breaking of the crystal.
And he succeeded. And failed.
The still blue crystal lingered in his grasp as he stared up at it. Adorning it's vibrant color, though, was the success. Red runes inscribed all along it's surface, permanently carved into it's surface laid the groundwork. There was no bleeding the crystal. That's what he learned early on. In his other hand the knife he'd taken originally. Now alchemized and seething with the Dark.
He finished etching the last rune with the tip of the knife. And waited. To complete it, he'd have to set out and do what
Darth Carnifex
had demanded of him in the first place. Kill a Jedi, or anyone of the light truly, and empower the runes with their suffering. A failure, and a success.
