The Gancanagh (Irish: Gean Cánach, meaning "love talker") is a seductive male fairy from Irish mythology known for enchanting mortal women, who then pine away and die from longing.

Description and Legend
- Appearance: The Gancanagh typically appears as a handsome, well-dressed wanderer.
- The "Smoke" Association: He is famously depicted carrying a clay pipe, but is never seen smoking it because fairies supposedly detest smoke. The pipe is believed to be a prop to make him appear more appealing or "refined" to mortal women, a "bad boy" look in past times. The association with "smoke" in his moniker "The Smoke Veiled Tempter" comes from this object and the mist (or lack of a shadow) that is said to accompany his approach.
- Seduction Tactics: He uses sweet words ("honey-mouths") and charm to quicken immense desire in women. Some myths suggest an "addictive toxin" is on his skin or lips, making women literally addicted to him.
- Consequences: Once the woman is infatuated, he vanishes. The victims waste away and die from the withdrawal and heartbreak, or potentially even fight each other for his love.
In Modern Culture
The Gancanagh archetype continues to appear in modern fantasy literature. For example, the character Oak in Holly Black's The Folk of the Air series is identified as a Gancanagh, known for his charming and frivolous nature in romance. The name is often used to symbolize the perils of unchecked desire and fleeting temptations.
The phrase "The Veil of Smoke" may also refer to specific book titles, such as a volume in the TimeDrifter Series, but in the context of the Gancanagh, it relates to the mysterious mist surrounding the fae and his unlit pipe.
