Inner Worlds

The Inner Worlds referred to the inner-galactic planets of the Mutter's Spiral galaxy, as opposed to frontier worlds on the Outer Rim. (AUDIO: Bad Day in Tinseltown)

During the Second Dalek War in the 26th century, the Auros populations were attempting to go to the Inner Worlds after their planet was destroyed. (PROSE: Prisoner of the Daleks)

When a phase shifted Cyber-Warship exploded, because its co-ordinates were set for the Inner Worlds, it left a "scar in hyperspace" that formed a wormhole from the Inner Worlds to an Outer Rim planet. (AUDIO: Bad Day in Tinseltown)
