Tree of silver wings

"In the Garden grows a tree of silver wings. The leaves are ruin, the bark disaster. Of the seeds we do not speak."

- Ruin Wings flavor text

The tree of silver wings is a mysterious entity referred to by multiple sources, typically in association with either the Black Garden or the metaphorical "garden" allegorically used to describe the state of reality predating the universe. It once existed alongside the Gardener and Winnower, until the two entities began fighting with one another and destroyed it in their struggles.
