Prospero Subsector

The Prospero Sub-sector is the part of the Ultima cube around the Prospero System, charted on this map as Forzare. Forzare is the hub of the Prosperan Rift and contains, within the same well, Magnus’s ruined homeworld and the Planet of the Sorcerers.

Several episodes are associated with this region: Russ’s censure of Magnus, the Burning, and the later Rubric wars. Axandria shares the chart with the sub-sector. The map does not add a second marker for a Prospero system.

The sub-sector remains significant as the setting of the events that shaped the history of the Thousand Sons. Unofficial maps retain the Ultima cube as its parent and treat forzare-system as the Prospero well.
