Selforge City has a waypoints network allowing citizens to freely access any part of the city, though most usually stick to the parts they are familiar with, since each section is optimally suited to its residing population. The "crossable mirror" borders are just a trick to coherently make sense of a flat demi-plane that would end up rejoining itself like a spherical world does.

Selforge City evolves alongside its population, so the changes are permanent actualities rather than temporary reflections, and while contents are adapted in real time on an individual basis (in a library each citizen will find the book they want), the structures are only transformed when the residing population durably wishes it so.

Mother's/Fathers' Day are great celebrations, and citizens' birth and comings of age (baby => child => teen => adult) are just as important in personal circles, followed by a variety of sistehoods-related events. Aside from these, recreative festivals of all kinds are the rule, often themed after trendy Inner Planes and promoted by adventuring fanbases among citizens (imagine a cosplay event but for an actual world).
