Location from The Bridge Kingdom by Danielle L. Jensen
The treacherous waters between continents — the reason the bridge exists, because sailing across is possible but expensive and dangerous enough that overland trade through Ithicana is worth the tariff.
The strait between continents is the geographic reality that makes the entire series possible. If the crossing were easy, Ithicana's bridge would be a convenience rather than a necessity. Because the waters are genuinely dangerous — storms, currents, reefs — overland trade through the bridge is faster, safer, and cheaper despite the tariffs. This economic math is the foundation of Ithicana's power and the reason Maridrina and Valcotta both want to control the bridge rather than simply sail around it.
Open ocean between the northern and southern continents, broken by the island chain that Ithicana occupies. The waters are dangerous: strong currents, unpredictable storms, reefs, and sea conditions that make navigation treacherous. Ships can cross but it's slow, risky, and expensive — which is exactly why the bridge is worth killing for.
