Gardener (Sonnenblumen)

One of the human survivors who had been saved from the destruction of Dawn 10000 by Coloth and Rich settled in Dawn's HQ reality of Spiral and busied themself with becoming a gardener, having petitioned Kinan Jans to relax Spiral's utopian laws of physics to allow it to be something of a challenge.

However, they also accompanied Coloth and Rich on some of their trips to other universes in the 10,000 Dawns, hoping to find closure. Six months or so after the destruction of Dawn 10000, they followed the two to a Dawn where they had to stop an Invisible Inferno from attacking the neighbourhood of the gardener's counterpart; using their own key, they were able to enter their other self's house, finding it almost entirely identical to their own. The one discrepancy was Massacre on the Orient Express taking the place of Murder on the Orient Express on one of the shelves. Filching it impulsively, the gardener took it back to Spiral, unaware that the being of light who had been the Inferno's target was hiding in its pages.

After the gardener read through the book in their garden, the being of light, and many others who had found their way back, entered their sunflowers. This caused all the sunflowers to point towards the portal to their native Dawn instead of pointing to Spiral's Sun. Coloth eventually realised what this meant and, absorbing the beings of light into his own vegetal body to transport them, travelled to the ruin Dawn with Rich and the gardener. There, while most beings of light returned to the Sun, this one took advantage of the reflective glass floor of the melted city to jump into the gardener's reflection and then psychically explain the whole situation to them. To their surprise, the gardener then told them of their intention to remain in the ruined Dawn and help rebuild it; as part of their garden (albeit in a new form), they still considered the being of light to be their responsibility.
