Chinvat Bridge Concept
A concept "sketch" for a location in Two Halves, called the Chinvat Bridge.
The Chinvat Bridge is a concept in Zoroastrianism, a sort of bridge to the afterlife. You are judged on your "righteousness" — affecting whether the bridge is thin and precarious, or wide and stable. Some interpretations also associate the Chinvat Bridge with the Milky Way.
While to explain much about it would get into spoilers, those are a few points that made me feel inspired enough to try sketching out some ideas for it.
