Rorschach figured out the general structure of the device.
The front of the Airship cabin was the scene of the confrontation between the Priest of Song Rank and the Chief Mage. To balance the weight, the heavy device was naturally fixed in the middle section. By the time the avatar rushed into the crashed Airship, the core metal sphere was no longer a nearly perfect sphere. Joseph Rorschach used the Decomposition Skill to cut open the outer shell and investigate.
What he saw were large Oscillation Crystals embedded between onion-like spherical shells, arranged in a staggered pattern. At the very center was a clear Crystal Lens. Though it had been "upgraded" to a battle-damaged version and was shattered to pieces, he could still tell it had been a high-end model when it was manufactured.
