As a natural crossroads between Hutton & Doverdale, Illyria & Hitachiota, and trade routes extending from Kadambur, Guzamala was a thriving trade hub.
Unsurprising that Doverdale wanted to annex the system
Doverdale overwhelmed Guzamala's meager navy and imposed a blockade
But the Doverdaleans haven't been able to overcome the planet's Mandate-era ground batteries or numerous partisan troops to seize the planet itself
The blockade has done extensive damage to the planet's economy, but with two unsettled garden-like continents, there is little chance that a Doverdale siege will succeed.
Ground batteries may eventually run out of missiles, but only if Doverdale can provide them with threats faster than they can build new missiles.
Even after landing ground troops, Doverdale will face significant resistance. The longer the blockade lasts, the better trained all those partisans will be – and the more guns that can be smuggled onto the planet.
