This morning I made a blog post titled World Building in the Twilight Time. It was actually a reference to a world building article in a zine called Twilight Time, but the title of the blog post got me thinking. A world set in the “twilight time” of its civilization(s) can make a fascinating setting. While twilight is more commonly used to refer to dusk, it can also refer to dawn:
Twilight: The soft, diffused light from the sky when the sun is below the horizon, either from daybreak to sunrise or, more commonly, from sunset to nightfall … the period in the morning or, more commonly, in the evening during which this light prevails … a terminal period, esp. after full development, success, etc.
Therefore, a world or civilization set in its twilight time would probably be on the verge of falling apart after a long period of development and success (think fall of the Roman Empire), but it could also refer to the beginning stages of such a civilization.
Today, free-write about a civilization entering its twilight years–of either variety.
