By his twenty-fourth year, Esigie had been at the academy for six years and had reached Forge Peak.
The top of Level 5. One sub-tier below the Mantle breakthrough that would mark his entry into Level 6 the level where aura became visible, where the body's projection could extend beyond the skin, where the casual distance between 'capable warrior' and 'formidable power' was definitively crossed.
He didn't cross it.
For three years, he sat at Forge Peak and did not advance. His cultivation sessions continued nightly, disciplined, guided by the Arbiter but the energy he pushed through his channels didn't push against the Mantle wall. It circulated. It compressed. It refined. It built density and efficiency and structural integrity at a level that the Arbiter described as 'foundation compaction' and that the outside world interpreted as 'stagnation.'

I let them think I'd peaked.
The academy's cadets, the instructors, even Agbonifo they all reached the same conclusion. Forge Peak was Esigie's ceiling. Impressive for a slave, remarkable for his age, but ultimately limited. The prodigy who burned bright and flattened. It happened. Talent without resources, without noble-house support, without the cultivation aids and advanced training that the wealthy cadets had access to talent alone hit a wall, and the wall was usually Level 5 or 6.
They were wrong. But their wrongness served me.
At Forge Peak, I was unremarkable. A data point that had peaked. Not worth watching. Not worth worrying about. The noble cadets who had eyed me with suspicion in my first year stopped caring. The instructors adjusted their expectations downward. The administration filed me under 'adequate' and moved their attention to cadets with higher ceilings and brighter futures.
I became invisible again. The ghost, returned. And in the invisibility, I did the real work.
The foundation I was building the compressed, ultra-dense energy configuration that three years of deliberate stagnation had produced was unlike anything the academy had seen, because the academy didn't know to look for it. Forge Peak was Forge Peak. The numbers were the numbers. What the numbers didn't show was the quality the purity, the structural integrity, the near-perfect efficiency of channels that had been running optimized cultivation protocols designed by an analytical system that processed combat data and energy flow patterns with inhuman precision.
When I finally broke through when the Mantle wall came down the foundation beneath it would be so solid, so compressed, so overbuilt that the breakthrough itself would carry a force that reflected not six years at Level 5, but six years of building something that Level 5 was never designed to contain.
The Arbiter called it 'potential energy storage.' I called it sitting on the score.
Lagos boy to the end.

Meanwhile, the magic grew.
Hidden. Always hidden. The aura stagnation was the cover while the world watched his aura plateau, his mana advanced through the levels with a speed that the Arbiter described as 'aggressive but sustainable.'
Caster Intermediate to Caster Peak. Then the wall. Then through it: Weaver Basic. Level 4 magic. The level where spell construction became an art layering effects, combining elements, building magical architectures of increasing complexity.
Then deeper. Weaver Intermediate. Weaver Peak. The wall again thicker this time, the Level 4 to Level 5 boundary that separated professional mages from court-level practitioners.
Conduit Basic. Level 5 magic. At twenty-four.
His mana reserve had expanded to a capacity that the Arbiter measured as 'approximately equal to a formally trained Conduit with seven additional years of cultivation.' The efficiency of his dual-soul architecture the wider channels, the deeper pools, the resonance between systems that the twenty percent of the synchronization text had given him just enough insight to exploit was producing magical advancement at a rate that outpaced his aura progression by a factor of three.
He could cast combat spells now. Not the marble-sized air compressions of his first experiments real spells. Fire manipulation. Wind cutting. Earth reinforcement. Shield constructs that could stop a Level 3's sword strike. The techniques from the three scanned books, practiced in the dead of night, in locations the Arbiter identified as outside any surveillance perimeter, refined over years of solitary work.
Nobody knew. Not Aighon, who slept beside him in the cramped dormitory room and would have been thrilled. Not Osawe, who monitored everything and would have been terrified. Not Ehize, who suspected something and would have been fascinated.
The second river ran deep and silent, and the world above it saw nothing.
