This chart, created from
The Traveller Map site, shows a portion of IV Quadrant (Rimward and Trailing of Charted Space) that displays Realm Space in context with the sectors of both the
Orion OB1 Association and those mapped by
Turokan's Rim Expedition.
Realm Space (not labeled) essentially comprises the large cluster (or massif) within the rift complex upon which this chart is centered.
(Not depicted are the unmapped sectors traversed by the Solomani Reconnaissance to the Rim. From Coreward-to-Rimward, that Reconnaissance followed those sectors along the "x" axis labeled "0.")
