Core reaches space

Star chart showing Black Cluster's edge (far left).

The Black Cluster is a region of space in the Alpha Quadrant which includes a portion of the Federation, the Breen Confederacy and the Romulan Star Empire, as well as a stretch of the Federation-Romulan Neutral Zone. (Last Unicorn RPG module: The Way of D'era: The Romulan Star Empire, ST reference: Star Charts)

Star Charts shows the Black Cluster in the Alpha Quadrant, away from the Beta Quadrant borders of Romulan space. With the Last Unicorn RPG map showing a different arrangement, it seems the two different maps show different angles of the three-dimensional borders.
This might be the same black cluster seen in TNG episode: "Hero Worship".
