The returning garden
An astronomical catalog identifies an orbiting body, not a geological map. We know neither the age of these imagined lava surfaces nor whether this planet has active volcanism, erosion or continents at all. The landscape provides a fictional disturbance through which to examine how botanical life and its partners might return [2]. Across the wet watershed, pioneer films occupy bare seams, small fans gather on weathered ledges and mature hollow crowns rise above river mist. The progression is arranged across space so that several stages can be compared in one image. It does not document an evolutionary sequence or supply a recovery rate. Radial nutrient carriers move between the patches. Organic fragments and mineral particles accumulate in sheltered pockets; larger colonies alter drainage and shade once they establish. The supporting biology therefore helps create the conditions under which the botanical community can expand, while also depending on its output. Retreating storm clouds unify the terrain through a single illumination field. The water, geology and life remain assumptions, but their relationships are intentional. This is a proposed working landscape: starlight supplies energy, weather redistributes water, and many small exchanges turn isolated growth into a forest. Viewpoint: Recovering forest watershed.
The imagined scene
The host system is real. All alien organisms, robots, societies and social histories are fictional. Moons, rings, terrain and weather are artistic assumptions unless specifically supported by a cited source. These images are not calibrated simulations of the sky.
The scientific anchor
Kepler-1649 c is a transiting planet around Kepler-1649. Its saved radius is 1.06 (+0.15 / −0.10) Earth radii and its orbital period is 19.53527 ± 0.00010 days [Vanderburg et al. 2020]. This scene explores water, disturbance and ecological succession. Pioneers, nutrient carriers and mature colonies form an invented succession mosaic across disturbed terrain. All weather, vegetation and other life are fictional.

NASA composite catalog values may combine different papers. Errors and upper/lower limits are retained. “Calculated Value” means derived or estimated. Msini is a minimum mass. Missing values are unknown. A multiple-star system’s single stellar row does not describe every component. Equilibrium temperature is not a measured surface temperature.

What about life?
Passes a deliberately broad 0.25–1.75 Earth-flux triage window. This is not a calculated habitable zone or evidence of water or life. Atmosphere, surface pressure, water inventory, stellar activity and orbital history remain unassessed. No confirmed life; no planet-specific biosignature literature review in this release.
