염매 (yeommae) is a type of black magic in Korean shamanistic tradition where a living person is sealed inside a clay jar and starved to death, so their spirit — full of rage and suffering — can be weaponised as a 원귀 (wongwi), a grudge ghost. Because the death is deliberately engineered rather than natural, the spirit cannot follow the normal path to the afterlife and is trapped in a state of violent resentment.
A 원귀 (wongwi) is a ghost specifically defined by unresolved han — deep, accumulated grief and resentment. Unlike an ordinary ancestor spirit, a wongwi cannot move on and is believed to cause sickness, misfortune, and death to the living. Korean folklore treats wongwi as among the most dangerous supernatural beings precisely because their anger is justified — they were wronged in life.
고희 (gohwi) refers to a person's 70th birthday, considered an especially auspicious and rare milestone. The accompanying 고희연 is a formal celebration banquet, historically a grand affair for nobility and royalty. In court dramas, such events are also political stages where royals are expected to perform health, composure, and lineage strength — making a child fainting at one a deeply embarrassing omen.
The 익선관 is the distinctive black hat worn by a Joseon crown prince (세자) during everyday palace life — its two wings curve gently upward. It is not a battle or ceremonial helmet but the mark of a prince's daily royal status. The king having one made for a now-dead young nobleman signals how much political hope he had placed in that child.
In Korean folk belief, peach trees (복숭아나무) are thought to repel evil spirits and illness carried by them, because the bright red-pink fruit was associated with the yang (양) force that counters dark supernatural energy. Boiling peach branches and drinking the liquid, as the villagers here are doing, is a traditional folk remedy used when people suspected a disease had a supernatural cause rather than a purely natural one.
괴질 (goejiil) literally means 'strange/uncanny illness' and was the historical Korean term for epidemic diseases that doctors could not identify or treat — cholera outbreaks in the 18th and 19th centuries were famously called this. In the drama's palace court meeting, officials brush off the village sickness as a minor cold (고뿔), so the physician's use of 괴질 signals the situation is far more alarming than the court wants to admit.
Writing and exchanging personal poetry (시, si) was a core Confucian scholarly practice in Joseon. A prince composing poems and sending them as letters (서찰, seochal) to a trusted elder was both an act of filial affection and a demonstration of his classical education. The fact that this collection of poems is described as the crown prince's only remaining relic gives it enormous emotional and spiritual weight — in Korean tradition, a person's written words carry a trace of their 혼 (hon), their soul.
비현각 was the name of the actual study hall within the East Palace (동궁) complex in Gyeongbok Palace where the Joseon crown prince received his education and conducted official studies. Sealing its door handle with the dead prince's poetry is a ritual act of spiritual containment — the idea being that a ghost can be 'anchored' or suppressed at the physical location most closely tied to its identity in life.
업보 is the Korean rendering of the Buddhist concept of karma — specifically the idea that suffering in the present is the fruit of wrongdoing in a past life or one's own earlier actions. Using this word here is pointed: the character is not expressing sympathy but a verdict, framing the king's collapse as cosmic justice for crimes committed decades ago. In Korean everyday speech, 업보 carries the same weight as 'you reap what you sow,' but with a more fatalistic, Buddhist undertone.
In Joseon law, disturbing a royal burial site was classified as 대역죄 (daeyeokjoe), treason of the highest order, punishable by death for the person responsible and potentially their entire family. The crown prince's tomb would have been consecrated ground managed by the state. The princess immediately volunteering to bear all legal responsibility shows how desperate the situation is — she is knowingly placing her own life on the line.
A 몸주신 (momjusin) is the personal tutelary spirit that 'rides' and protects a particular shaman (무당). In Korean shamanism, a shaman's power is not their own — it comes from this bonded deity. Asking whose 몸주신 an unknown spirit is serves as a kind of supernatural ID check: the questioner is trying to determine the spirit's lineage, authority, and therefore how dangerous it truly is.
타살감흥 is a rhythmic exclamatory phrase used in Korean mudang (무당) shamanistic ritual, similar to a chant or war cry shouted during a gut (굿) ceremony to summon or engage spiritual forces. Shouting it while fleeing is darkly comic — the character is invoking ritual battle language in a situation of pure panic, which is very much in keeping with the drama's blend of horror and absurdist humour.
귀매 (gwimae) is a specific category in Korean and East Asian supernatural taxonomy — spirits that are not merely dead humans with grudges, but entities that have accumulated so much dark energy they have transformed into something closer to demons. The distinction matters in shamanism: the method used to subdue or expel a wongwi (grudge ghost) may be completely useless against a gwimae, which explains the alarm in the character's voice.
