The Marrow: A Humorous Guide to Silksong’s Lava-Filled Tutorial Cave

The Marrow is the first area players will traverse after leaving Bone Bottom and Mosshome in Hollow Knight: Silksong. It is a mixture of underground tunnels and lava pools, and it marks the first steps toward the Citadel in Pharloom. The place is basically a cave that looked at a tutorial and said, ‘Let’s add lava.’ As of 2026, guides are still being updated as new details emerge, but here is what is known so far.

Benches, Fleas, and a Very Loud Beast

There are four benches in The Marrow for resting and healing. The flea caravan sits at the second top bench and right below in the small square to the left down the middle shaft. The Bell Beast, at the top-most portion of The Marrow map marked by the silver disk, is the only main boss fight in the area and unlocks fast transport stations across Pharloom. Nothing says ‘welcome to the neighborhood’ like a giant bell-themed creature that wants to flatten Hornet.

Sharka can be found immediately after the bone gate is opened and at the start of The Marrow. Players should speak to them to gain new map pieces and map markers. When players enter new areas like the Deep Docks or Hunter’s March, Sharka will also move to that same area. The top right path adjacent to Mosshome leads to a dead-end room filled with bells. The path right below the top right path leads into Hunter’s March; players will need Swift Step and the Glide ability to traverse there properly. A mini-boss also blocks the path, because of course it does.
