Howling Cliffs

A wasteland in the far northwest part of Hallownest. Sparsely populated by enemies, the ground is littered with the corpses of bugs large and small. At the western end, a powerful wind will blow the Knight back, preventing them from moving any further.

Sub-area: Joni's Repose
A grotto filled with blue butterflies to the east of where Cornifer is located. After some platforming, the ghost of Joni can be found near an altar. It is here that the Charm Joni's Blessing can be obtained.

Sub-area: Stag Nest
The birthplace of The Last Stag, and all other Stags in Hallownest, reachable only through unlocking every other available Stag Station. Littered with Stag corpses, but also one freshly hatched egg, signalling the hope for Stags to live on.

Nightmare Lantern Chamber
The Knight needs to collect both the Mothwing Cloak from the defeated vessel in Greenpath and the Mantis Claw from the Mantis Village before being able to access The Howling Cliffs, and in turn being able to access this room.

This room serves two purposes, both revolving around the Grimm Troupe. This room allows the Knight to summon the Grimm Troupe into Dirtmouth and access the DLC. But this room also serves the second purpose of being able to banish the Grimm Troupe from Hallownest and complete the DLC’s alternative ending.

Trivia

 * This is the area the Knight is seen traversing through in the opening cutscene. At the northeast part of the cliffs, the same ledge with the lamppost can be found that the Knight jumps at the end of the cutscene.
 * Based on a Lore Tablet in this area, once a bug reaches beyond here, they will lose the "precious mind" that the Kingdom of Hallownest grants.
 * Once the Crystal Heart has been acquired, it is technically possible to super dash from a ledge on the eastern side of the Howling Cliffs over to the Stag Nest without having to unlock every Stag Station.
 * It is also possible to reach Stag Nest by having the Monarch Wings and luring 1-2 Vengeflies to nail-bounce to reach the ledge.
 * The northeast part of the Howling Cliffs connects to King's Pass when jumping off the ledge, but using Crystal Heart here will skip King's Pass and instead makes the Knight end up directly in Dirtmouth.
 * Due to a glitch with the physics, if the map is pulled out while being pushed by the wind, the Knight would be pushed faster.
 * This is the only area that doesn't have enemies exclusive to it.
