Simple Keys are Items in Hollow Knight. They can be used to open simple locks. Each key can only be used once.

Use

There are four locations that can be opened using Simple Keys:

Hornet is the mysterious princess-protector of Hallownest’s ruins, a major character in Hollow Knight and the playable protagonist of Hollow Knight: Silksong. She wields a Needle and thread with deadly prowess.

Hornet is captured by outsider bugs and brought to their kingdom, Pharloom, but she escapes her cage before arriving at their destination. She then must battle foes and solve mysteries to ascend on a deadly pilgrimage to this kingdom's peak.

Health is represented as Masks, shown in the upper-left corner of the screen. Hornet starts the game with 5 Masks and can obtain more. Health is lost by taking damage, either from enemies or from environmental hazards. Health can be regained by the use of the Bind ability consuming a full Silk spool.

Lifeblood Masks, granted by Lifeblood needles, are temporary masks.

Silk is represented as a spool below the health indicator. Thread is consumed when using special abilities, including a form of Focus named Bind. Striking enemies with the Needle fills the spool by two laces. When the spool is full, the symbol representing the side of the spool left to the health indicator is filled.

The Needle is Hornet's main weapon. Not only can she use it to slash or block attacks against enemies, but also to dash forward, stab, and bounce up above them. She can also use it alongside her abilities to deal greater damage or as a grappling hook.

Tools are special items classed by categories, equipped on a Crest with limited slots. They can be used as throwing weapons or defensive aids without costing Silk. Crests and Tools can be changed when sitting on a Bench similar to Charms.

Abilities consume Silk thread to use them.

Hornet can collect and keep various items throughout her journey, which are stored in her inventory. They can be related to specific quests.

The following areas have no confirmed name, although the names used were mentioned in the official announcement. Other mentioned names include "Bonebottom", "Moss Temple", and "Soaring Warlord's Tower": "Coral Forest", "Gilded City", and "Lake of Fire/Bone Forest".

Garmond and Zaza are two NPCs first revealed in the Hollow Knight: Silksong announcement trailer. They are on a quest to find a new home. Garmond appears to be the rider, while Zaza appears to be mount.

Garmond and Zaza only appear once in the announcement trailer; they are seen during the "New Quests" segment. Within a dark, murky hallway with a visible curved lattice pattern in the background, Hornet is shown leaping over the two as they charge forward through a small group of enemies, while Garmond makes a loud vocalization.

They were later revealed in a blog post, which states that the two are on a quest to find a new home. Garmond is described as being rambunctious and chatty, while Zaza is noted to possibly be "the brains" of the two.

Elder Hu was a travelling sage who sought to purify the borderlands of Hallownest from the Infection. He reached the Mantis Village, but his own Infected mind made him see the Mantis Lords and the Tribe as afflicted by the plague. The Mantises killed him after he attacked them. A memorial was erected in his name above the gates to the City of Tears, his tunic and bead necklace resting on top of it.

The spirit of Elder Hu can be fought at his memorial after acquiring the Dream Nail. Still deluded in his experience with the Mantis Tribe, he warns the Knight. After his defeat, the spirit becomes aware of his madness-driven mistake. He realizes his own death before shattering into 100 Essence to be collected by the Dream Nail.

Elder Hu has two attacks in addition to being able to teleport:

Ring Slam: Elder Hu summons a row of rings in midair, interspersed with several safe gaps, before quickly slamming them all down onto the ground simultaneously.

Ring Curtain: Elder Hu summons pairs of rings that slam down on the ground, beginning from the edges of the arena and moving towards the centre.

Teleport: Elder Hu warps from one area to another to avoid attacks or set up his own.

The ring attacks require very precise movements to dodge as they come out quickly. The Shade Cloak is highly recommended, although not completely necessary. Elder Hu remains in place during the attacks, and his floating pattern is low enough to the ground, where attacking with the Nail is possible. Dodge the rings and get in some hits in between. Eventually, the rhythm of the attacks is easy to follow and the Knight should have no problem timing dashes and attacks.

Alternatively, the Knight can use Shade Cloak to dodge the Ring Slam attack and use Howling Wraiths/Abyss Shriek along with a Spell build (such as Shaman Stone, Spell Twister, Soul Catcher, and Soul Eater) to quickly finish him off.

How to Acquire

  • One can be bought from Sly in Dirtmouth for alt=Steel Soul Jinn is a Merchant in Hollow Knight. She only appears in Steel Soul Mode, replacing Confessor Jiji. Jinn resides in the locked cavern by the base of Crystal Peak in Dirtmouth, where she has been sleeping. She has unseen masters who do not seek order. Jinn speaks in rhythm and claims to be too young to tell anything about herself beside her purpose of providing and trading. Her metallic body cannot take damage, although she still reacts to strikes at her. Steel Soul Jinn replaces Jiji in Steel Soul Mode, as the difficulty mode's permanent death makes Jiji's service useless. She is disgusted by Rancid Eggs, but will still buy them for Geo 290-449 each, as a favor to a friend which she claims appreciates them. This is also an excuse for her to get rid of the Geo she accumulated after helping or hurting other creatures, despite not wanting any. Steel Soul Jinn is located on the very east side of Dirtmouth, within a cave that requires a Simple Key to open. The friend she mentions who likes Rancid Eggs is most likely Confessor Jiji, who is willing to offer her services for them. Jinn is one of the few NPCs who can be "hit" with the Nail without taking damage. An upcoming enemy revealed in the Hollow Knight: Silksong trailer bears a striking similarity to Jinn. It is also a companion to Steel Assassin Sharpe furthering some sort of motif of "steel" between the characters. Jinn is mistakenly referred to as male in some translations of the game. 950.

Trivia

  • The sprite for the Simple Key is called the "graveyard key" and both a "Bath house key" and "Waterways key" exist in the game files implying that Jiji/Jinn's cave, the Pleasure House, and the Royal Waterways were each originally planned to be opened by these unique keys.
