Rukiilla

Rukiilla is a fictional planet featured in the science fiction novel "The Last Starship" by Mark T. Stinson. It is depicted as a humid, jungle-covered world with a dense atmosphere. The planet's surface is characterized by towering trees, large, exotic flora, and a wide variety of alien fauna, many of which are described as bioluminescent. Rukiilla experiences frequent rainfall and has numerous rivers and swamps.

The indigenous sentient species of Rukiilla, known as the Lumina, are described as amphibious beings who have adapted to their watery and dimly lit environment. They are depicted as having a tribal society and a deep connection to the natural world of their planet. The Lumina are often portrayed as wary of outsiders due to past encounters with off-worlders.

In the narrative of "The Last Starship," Rukiilla serves as a significant location where the protagonists seek refuge and essential resources. The challenging environment and the presence of the Lumina present obstacles and opportunities for the crew. The planet's unique ecosystem and the Lumina's culture are integral to the plot, influencing the characters' decisions and the overall development of the story. Stinson uses Rukiilla to explore themes of environmental adaptation, cultural misunderstandings, and the search for survival in an unknown galaxy.
