Hirsch's concept of 'postmemory' — memory transmitted across generations not through lived experience but through stories, silences, and images — maps with disturbing precision onto the archipelago's inheritance system. In this anchor, islands are not only created by direct experience but can be bequeathed. A cartographer may inherit an entire island-chain from a dead predecessor, complete with its name, its borders, and its emotional weather — without ever having set foot on it. The lacunae (gaps, silences, the islands that were never mapped because the trauma of mapping them was too great) become the archipelago's most politically contested terrain. The German legal research context resonates here through the Konkursordnung's logic of estate administration: what happens to the memory-islands of the dead? Who is the rightful heir? And what does it mean to administer — or liquidate — someone else's interior geography? Forgetting, in this frame, is not erosion but disinheritance.
