Back in the secure Apex Command lab, the atmosphere was charged. The massive, jagged fragment of the Nexus Pillar from the dimensional realm was secured in a containment field. It pulsed erratically, its chaotic energy resisting the A.D.B.G.'s stabilizing field.
Kellan, though exhausted, focused immediately on the fragment. They had eight minutes in the dimension; the Nexus fragment was proof of the Architect's flaw.
[Optimal Insight (Level 3) Activated! Target: Nexus Pillar Fragment. Sub-Optimal Point: Excessive reliance on raw chaotic energy (high energy, low stability). Optimal Synthesis: Purify chaotic energy into a stable, high-output energy core.]
"This fragment is the Architect's central design flaw," Kellan explained to Lyra and Dr. Roth. "It's pure, condensed dimensional energy, but the Architect's sub-optimal programming makes it unstable. If we can purify it, it will be the most powerful, stable energy source on Earth."
Kellan prepared the Synthesis. He combined the purified Apex Shard Dust with the raw Nexus fragment. This was the most dangerous Synthesis yet, requiring absolute precision.
Lyra, standing beside him, was the key. "Tell me the precise frequency of the fragment's instability peak," she commanded, her Absolute Energy Control ready.
"48.01 kilohertz. Introduce a perfectly sustained counter-frequency at 47.99," Kellan directed. "We're not stabilizing it; we're using its own instability to force it into perfection."
Lyra's golden energy flowed into the fragment. The containment field roared as the raw dimensional power clashed with Lyra's perfect, controlled counter-frequency. The clash wasn't destructive; it was purifying. The jagged fragment melted, then reformed into a smooth, silent, palm-sized crystalline structure pulsing with clean, brilliant white light.

[A.N.C. Status: Integrated into Apex Command. Power Output: 5000% increase over previous base power.]
The Apex Command instantly surged to life, every system operating at peak efficiency. The core of their defense was now a Nexus of controlled dimensional energy.
"The Apex Nexus Core," Kellan said, holding the pristine object. "The Architect was building a flawed weapon; we turned it into our ultimate defense."
Meanwhile, Dr. Roth was analyzing the residual data pulled from the Nexus fragment—the Architect's building plans.
"Kellan, the Architect wasn't building the anchor randomly," Vivian reported, her hyper-focus absolute. "It was using the coordinates supplied by a terrestrial signal. Someone on Earth is guiding them."
[Optimal Insight (Level 3) Activated! Target: Terrestrial Signal Source. Assessment: Signal is utilizing a highly complex, yet fatally flawed encryption pattern—Alistair Finch's original sub-optimal research code.]
"Finch," Kellan's voice was ice-cold. "Even in his ruined state, his sub-optimal work is still being exploited."
Vivian overlaid the signal source onto the Nova Prime map. The final coordinate, the source of the guidance signal, glowed a menacing red.
"The signal originates from the Central Bank of Nova Prime's vault," Vivian stated, a hint of professional excitement in her tone. "Not the vault with the money, but the hidden vault containing the legal and technical documents that Finch stole from you in the first place."
Kellan finally saw the full, terrifying scope of the Final Vengeance Arc (as promised in the Chapter 13-46 planning). The dimensional entities were not just attacking; they were being led to the original source of Kellan's betrayal.
"They are trying to optimize the damage," Kellan realized. "The entity controlling Finch's remnants isn't after money; they're after the foundational legal documents of the Apex Core's technology. If they destroy those, my ownership is sub-optimal and unenforceable, even after Finch's collapse."
Kellan's vengeance was not complete. The Apex needed to protect the root of its own legality.
"This is the last stand against the sub-optimal past," Kellan declared, turning to Lyra. "Jax and the Apex Defense Force will secure the bank's exterior. Lyra, you and I are going into that vault. We end this threat at its source."
