inferred: Lexicanum's Nurth infobox has Segmentum, Sector, Subsector and System ALL EMPTY, and the article names no neighbour, bearing or theatre. There is nothing to place this world against, so the record claims no segmentum and sits on the unsurveyed rim. The position carries no information and must not be read as one — it exists so the novel resolves to the world it is actually set on
