We begin the story inside the Agreste Mansion, in the Atelier. Gabriel is standing in front of the monitor, engaged in a video call with the Louvre Curator (with the camera disabled).
Gabriel:....Why must you insist on seeing it?
Curator (Video Call): It is a rare and mysterious artifact. The specialists deemed it of unknown origin, a very, VERY rare find to come across.
Gabriel: How did you even learn that it's in my possession?
Curator (Video Call): I have my sources. But they weren't able to conduct research before it came into your possesion. Though i am curious as to why you want it, all i ask is that you turn over possession of the artifact for a few days.
Gabriel: Give me one good reason why i should even consider.
Curator (Video Call): You will be well compensated and be able to take them it after a minimum of 3 days. We will have the best team of analysts and specialists to take the upmost care during research. You will also receive any and all information we will have gathered and collected regarding the item. Should you be satisfied with our findings, we will ask you for an extension.
Curator (Video Call): Mr. Agreste, do we have a deal?
Gabriel:....(sigh)....Even i am curious to what it maybe. Very well, i'll have it ready.
Curator (Video Call): I will arrange everything on my end as well. You will not regret this, Mr. Agreste.
Gabriel: For your sake, i better not be.
Nathalie then walks in.
Nathalie: Is everything alright, Sir?
Gabriel: No, something has come up. Nathalie, contact the Curator's office to arrange a delivery.
Nathalie: Will do, but may i ask what would be the special package?
Gabriel: Nothing of importance...yet. Now go, i have something that needs "attention".
Nathalie turns and walks out of the Atelier. Gabriel turns around and steps in front of the Mrs. Agreste portrait. He then moves the paiting, revealing the safe box and opens it. He then pulls out a small stone Zweihänder-like sword.
Gabriel: Whatever this is, i feel great power from it. As if....electricity is coursing through me. Whatever they find...(raising it into the air)...will prove most helpful in tapping into it's power.
This will be another great story, i can feel it. Find out what happens next in Chapter 1: Beacon.
Also, here's what the "sword" will look like (it's not my work).
