In the final decades of Earth's environmental collapse, humanity's last hope was the Providence, a 2.3-kilometer generation ship carrying 1,200 carefully selected humans, 4,000 animal species, 8,000 insect species, 8,000 plant species, and the frozen genetic legacy of 50,000 more. Her mission was to find a habitable planet and establish a settlement before the human species vanishes forever. The ship had a living ecosystem with a fusion heart, an Organic Hull Sheath that heals her wounds, and advanced technologies including the Oculus AI, Memory Looms that preserve experiences, and a Quantum Entanglement Communicator offering a thread-thin connection to Earth.
The ship went through a series of crisis, e.g., rice blast fungus threatening the food supply, gravitational anomaly forcing the crew to vent water and flooding the agricultural decks, void-born teenagers attempting to hijack the ship toward a beautiful nebula, and connection signal lost with the Earth, and at Year 20th, it arrived at Avalon, a 94.7% habitable planet with purple flora, lavender sky and breathable atmosphere. The crew established a settlement and continued to grow a city on Avalon.
