In Hollow Knight: Silksong, Act 3 introduces the Dark Hearts quest, a hunt-type challenge that tasks Hornet with clearing away clusters of Void Masses scattered across Pharloom. These strange growths unsettle the citizens of Bellhart, and removing them not only fulfills the wish but also earns Hornet a valuable Mask Fragment.
Although there are over 40 Void Masses hidden across the kingdom, you only need to eliminate 12 to complete the quest. This guide highlights the locations that are easiest to reach so you can clear the quest efficiently.
How to Unlock the Dark Hearts Quest
To begin, advance to Act 3 and pick up the quest from the Bellhart Wish Board. Once accepted, your task is simple: track down and destroy at least 12 Void Masses scattered in different regions. Each Void Mass looks like a pulsating cluster attached to walls, ceilings, or platforms.
Void Mass Locations in Silksong
Below are twelve locations that are relatively straightforward to reach. Remember, you don’t need every one of them—just any twelve will be enough to complete the quest.
1. Shellwood – Under a Platform
From Bellhart, ride the elevator upward and head left. In Shellwood, you’ll find the first Void Mass clinging beneath a raised platform.
2. Shellwood – Beneath the Cliff
Continue west, then glide downward to discover another Void Mass tucked under a cliff edge.
3. Shellwood – By a Room Entrance
Stay low and keep moving left until you reach a large chamber. Near the doorway at the top of the room, a Void Mass is attached to the wall.
4. Bone Bottom – Ceiling Cluster
Head left through the lower passage and approach the bench near Bone Bottom. In this horizontal room, a Void Mass is lodged on the ceiling.
5. The Marrow – Hidden in a Corner
Teleport back via the Bellway or travel from Shellwood into The Marrow. Move left and descend until you spot a Void Mass wedged in a corner beneath a platform.
6. The Marrow – Vertical Room Corner
Glide down a tall shaft, then climb toward the upper left corner. A Void Mass is positioned high up on the platforms.
7. The Marrow – Roof by Red Bulb
Keep climbing to the top of the same vertical chamber. On the roof near a glowing red bulb, you’ll find another Void Mass.
8. Near a Bench – Upper Area Cluster
After passing a nearby bench, continue right. A Void Mass is stuck high on the wall in the next area.
9. Deep Docks – Vertical Room End
Head into the Deep Docks, moving rightward. In the second vertical shaft, climb to the very end to locate a Void Mass.
10. Deep Docks – By the Lava Platforms
Higher up in the Docks, turn left near lava platforms. One Void Mass is anchored to a side wall. Clear out enemies first, then use plunge attacks to destroy it safely.
11. Far Fields – Ceiling Cluster
Proceed right from the Docks into Far Fields. In an elevated chamber, a Void Mass sits on the ceiling surrounded by hostile bugs.
12. Far Fields – Under a Platform
Backtrack slightly, then drop into the lower sections. A Void Mass is hidden beneath a platform close to lava pools.
Completing the Quest
Once you’ve destroyed at least 12 Void Masses, return to Bellhart and report back at the Wish Board. Hornet will complete the Dark Hearts quest and receive a Mask Fragment, bringing you one step closer to maximizing survivability in Pharloom.
