Citadel

The Citadel is a late-game area in Pharloom. It is located at the very top of the kingdom. Hornet must ascend to the Citadel on her quest through Pharloom. The Citadel has been often described as "shining" and "holy".

Many of the Citadel's inhabitants have fallen prey to the deadly warrior Seth who guards a secret at the base of the Citadel.

Glimpses of the Citadel have been shown in the reveal trailer for Hollow Knight: Silksong and the press kit.
