Marston Fort
The decrepit Fort Aboor, on the wild edge of Marston Avenue as it joins Cole's Canyon, is sister to the nearby but slightly smaller Fort Stokke. Both testaments to Ikaanos' history, now abandoned by the Skyguard who judged their strategic value not worth the cost of maintaining them. But not demolished either... so prone to being taken over and used as bases by bandits when they judge the Republic's forces as spread too thin to enforce control for a while.
The residents of Marston Avenue would be grateful for any independent adventurers who decide to do occasional raider removal when the Skyguard are too distracted by external threats to prevent these forts being turned against the populations they once protected.
