Unidentified small citadel

A diminutive fortress constructed of stone existed on the world of Ziost. In the year 40 ABY, a section of the stronghold's perimeter had crumbled into a heap of stone—carefully cut blocks of stone that had been toppled by an immense power. Ben Skywalker observed the effects of time on all outward-facing areas of the rocks, yet he detected no evidence of blaster scoring, fusion, or any other familiar marks of combat.
