Earth (12th Century)

The Doctor proposes returning to Earth, the homeworld neither he nor Peri currently inhabit, as a refuge from temporal instability. Earth emerges not as a specific place but as an emotional construct, a planet of memory and longing where time’s fractures feel less jagged. It is a world of blue skies and familiar streets seen through Peri’s nostalgic eyes, where the Doctor’s companionship is more significant than geography. The planet’s identity is fluid, shaped by Peri’s personal ties and the Doctor’s momentary need for a place that feels stable, even if it isn’t. For these travelers, Earth exists less as a physical space and more as a psychological anchor, a planet that exists in their shared history rather than a temporal present.
