A Bridge of Ceremony?
An interesting detail: If you have the bridge built during a certain late-game funeral event that takes place in Bone Bottom, the ceremony will proceed as if the bridge isn’t there—the body will simply clip through it.
A Lifesaving Bridge is a simple Donate Wish in Hollow Knight: Silksong that provides a small but significant quality-of-life improvement to the Bone Bottom area by preventing accidental falls into Moss Grotto.
This quest becomes available on the Bone Bottom Wish Wall as soon as you have reached the Greymoor zone for the first time. Simply travel back to Bone Bottom to find the wish on the wall.
Approach the Wish Wall in Bone Bottom and select “A Lifesaving Bridge” to begin.


Make sure you have at least 300 Shell Shards. Accepting the wish will immediately deduct the shards and complete the objective. The builder, Flick, will get to work.

The bridge is not built instantly. You must leave Bone Bottom entirely (fast travel is a good way) and then return. The bridge will now be in place.
Your donation results in a tangible change to the environment, making navigation safer.
The path next to the elevator has a large, open hole leading directly down into Moss Grotto, making accidental falls common.

A new wooden bridge now covers the hole, allowing for safe passage.
