This is an idea that I've been kicking around for a while. I hope you get a few laughs out of it, at least.
Invenio… Iterum (Chapter 19)
“I believe I have made a breakthrough,” Callidus announced. Annie and Shadix stopped to look at him. “What sort of breakthrough?” inquired Shadix, crossing his arms. Callidus spread his arms out as if preaching. “It’s a breakthrough concerning the Mobius shards. I believe I now have the knowledge to construct a biological-slash-technological centrifuge powerful enough to synthesize shards into one mass, allowing a power greater than the sum of its
parts,” Callidus finished. He looked like he was expecting Annie and Shadix to clap for him. Now, Annie crossed her arms. “English, please?” She asked, exasperated. Callidus looked puzzled. “I’m pretty sure I was speaking English… unless you want me to explain in German, Mandarin, French, Spanish, Russian, Greek, or even Latin? Quam credo-“Shadix interrupted hastily. “Pretend we didn’t know anything about what you just said,” Shadix proposed. “How would you explain it to us then?” Callidus thought for a moment. A couple times he looked like he was about to talk, but stopped himself. Finally, he spoke. “I now know how to create a machine to combine Mobius shards into one, and that one is more powerful than the all the ones used to create it,” he said haltingly. Annie nodded. “Good,” she said simply. Callidus readjusted his glasses. “I’m going to need at least eight shards before I can combine them… plus the fact that the machine isn’t actually built yet, it will take a couple days to accomplish this,” Callidus admitted. Shadix shrugged. “It’s not like we’re pressed for time or anything.”
Arcus was tired. He had found seven shards by this point, and now he was ready to go back to the lab. He was sitting on the roof of a building, staring at one of the red, jagged metal pieces. Every so often, it seemed to pulse with red energy. It was subtle, just a circular ripple sweeping across the surface. It happened every few seconds, and Arcus couldn’t figure out what it was. He gave up, and stuck it back in his pocket. He stood up, and was about to summon his ‘electro-skateboard’ when he felt the force again. He was getting slightly annoyed. Occasionally it would just show up, and then disappear a few minutes later. He resolved to find what was causing it this time. He moved his arm like he was throwing a Frisbee, and ran. His disc flew a couple feet forward, and he jumped on. He crouched, and released. The disc jumped, and he landed on the next rooftop over. He bent forward, and he went faster. He kept on like this for several minutes. As he sped faster, he saw a glimmer in the corner of his eye. He twisted sideways, and leaned to his right to the point where his fingers were touching the roof’s surface. Sparks flew as he came to a stop. He saw someone standing on the edge of the building with his arms crossed. The person had a black cloak around his shoulders with the hood up. The stranger turned to face Arcus. On the inside, the cloak was white. In fact, it was so bright it was hard to look at. The stranger was wearing some sort of tunic-thing underneath the cloak. It was grey colored. No, wait… was it white? Or black? Arcus looked closely at it. At one point it was white, and then next moment it was black. Arcus shielded his eyes with his forearm. Arcus couldn’t see his face, but the stranger’s mouth curved into an amused smile. “Salutationes, filius de fulgur,” he said. His voice was… confusing. Arcus heard a higher, gentle murmur simultaneous to a deep, hateful, malicious growl. Arcus stepped forward, and dropped to one knee. “Fortitudinem et honorem to excubiarum,” Arcus quoted. He stood up, and took a step back. He shook his head, and a strong feeling of confusion washed over him. The stranger laughed a warm, benevolent, cheerful laugh alongside a spiteful, malevolent, cruel one. The stranger spoke. “Since you have deigned to speak our language, I will honor you in yours.” One part of the stranger’s voice sounded resentful, the other sounded pleased. Arcus had a million questions. He decided to ask the most prominent one. “Who, or what, are you exactly?” he questioned. “I am called Excubiarum, or as you say, the Sentinel.” The man we now know to be the Sentinel shot an annoyed look at the sky. “Unfortunately, they do not permit me to say more about such things.” The Sentinel looked back at Arcus. “My purpose is to maintain the dependendum, or balance. This man named Exitium, or Destroyer in your language, has upset that. I have been sent to guide you on the route of stopping him.” Thunder rumbled… which was strange, since there wasn’t a cloud Arcus could see. The Sentinel shot another annoyed look at the sky. “I have said too much already. Just know that I am not your enemy. Farewell, filius de fulgur.” The Sentinel turned back to the edge, and gracefully leapt off. Arcus ran to the edge and looked down. There was nobody there. Arcus rubbed his eyes. Had it all been a fatigue-induced hallucination? Arcus didn’t know, but he had even more questions now. The most puzzling one of all was the one he voiced aloud.
“What the heck does filius de fulgur even mean?”
