At ~2,500 words, this sophisticated diplomatic fiction demonstrates how empires can be undermined through commerce, culture, and careful persuasion rather than military force. Scerdilaidas of Illyria dies, creating a succession crisis—his son Pleuratus inherits an unstable kingdom pressed by Dardanians, Macedonia, and Rome. Sophonisba sees opportunity: send delegations (amber merchant, horse traders, genealogical scholar) to create "profitable neutrality"—economic facilitation of Celtic movement without military cooperation. Pleuratus agrees to a 10% passage fee arrangement, not the flood of Celtic warriors Sophonisba wanted, but something more valuable: a model showing other Roman clients they can profit from both sides while maintaining appearance of loyalty.
Scerdilaidas and Pleuratus were historical Ardiaean rulers. Philip V of Macedon was historically Rome's enemy. Celtic tribes (Boii, Insubres) occupied northern Italy. Illyrian kingdoms did maintain complex relationships with Rome and neighboring powers. The chapter operates within historical possibility—these entities existed with these relationships and could have made these strategic choices.
The chapter resists temptation to deliver perfect victory. Sophonisba wanted Celtic armies reaching Hannibal; she accepted economic facilitation and intelligence sharing. This realistic compromise is MORE valuable—it creates sustainable model rather than one-time dramatic gesture. The "profitable neutrality" concept demonstrates patient, systemic thinking: other Roman clients observing Illyria's quiet prosperity incentivizes them to explore similar arrangements. The three-delegation approach shows cultural sophistication—merchant (legitimate trade), horse traders (Celtic connection), scholar (cultural dignity) operate at different levels but serve same purpose. The genealogical argument ("Illyrians, Celts, and Galatians share ancient kinship") reminds people of forgotten dignity, awakening resistance through memory rather than declaration. Pleuratus's poem response ("eagle claims to guard the shore / but guards its own interests more") shows Rome's imagery is spreading. The key insight: economic incentives that can't be stopped without destroying the system itself undermine empires more effectively than dramatic defections that invite retaliation.
"This is how you undermine empires: not through dramatic defections that invite retaliation, but through quiet economic facilitation that can't be stopped without destroying the system itself. Sophonisba wanted Celtic armies; she got something better—a model showing every Roman client that profitable neutrality works. Watch Illyria grow richer while staying technically loyal. Now every other client is asking: why shouldn't we do that too?"

"The three-delegation approach is brilliant cultural diplomacy: merchants establish legitimacy through trade history, horse traders leverage Celtic connections, scholars appeal to dignity and ancient kinship. Each operates at different level, but all serve purpose of reminding Illyrians they have choices. The genealogical argument doesn't say "betray Rome"—it says "remember when you ruled these waters.""

"Pleuratus accepts 10% passage fees while drawing clear lines (no armies through heartland, Celtic protection of villages). This is realistic diplomacy—not perfect alliance but achievable compromise. More importantly, he's clearly cleverer than his father. His poem response shows he already thinks in Sophonisba's metaphors, which means he's already halfway convinced. The model will spread."
