Citizens of Ukivy can never agree on how their city should be laid out- so each year, they let the sun and soil decide. Before each spring’s last frost, there is a frantic rush to plant the right seeds in the right locations. Despite their best efforts, the result is never as they planned- each year is a seemingly random city layout. Some years your house is large and spacious, some years it barely blooms. The only constant is the city's central tree, which slowly grows with each passing year. Every autumn, citizens collect the seeds produced by their dwellings and recede into the central trunk, like a large migration to another time and place both familiar and unknown.
