The Planetary Allies of Zendar is a faction comprised of various sovereign worlds and star systems that are formally aligned with the Zendar Empire.

They are not subjects but allies. These worlds have forged strong, mutual alliances with the Empire, suggesting a relationship based on diplomacy and shared interests rather than direct rule.

They are key contributors to the Empire's power, bolstering both its economic and defensive might through their alliance.

The description identifies them as "sovereign worlds," which means they are independent, self-governing entities that have chosen to ally with the Empire, rather than being conquered or incorporated territories.
