|Menaces: Yearning, Burning|
It is linked to performing sunlight-related activities, primarily the smuggling of Sunlight-Filled Mirrorcatch Boxes, as it increases every time you fill a box at Avernus on the Surface or at Aestival.
If this quality rises too high, a series of random events will start happening, causing you to start opening Mirrorcatch Boxes uncontrollably, getting a Wound every time and increasing this quality even further. If you don't stop the chain reaction quickly by getting rid of all the boxes (either by selling them or throwing them overboard using the button in the Hold tab of the Gazetteer), you will die.
You obtain +4 to +7 x Menaces: Yearning, Burning by filling Empty Mirrorcatch Boxes, either at Aestival or on the surface at Avernus, and +1 x Menaces: Yearning, Burning on traveling to the surface. It also increases with some Dawn Machine-related actions at the Grand Geode.
You lose -2 to -3 x Menaces: Yearning, Burning by resting at Your Lodgings in Fallen London. The quality of lodgings does not affect the amount. You also lose all Menaces: Yearning, Burning by volunteering for surgery with the Cladery Heir.
Menaces: Yearning, Burning has different statuses according to your actions, defined by the number in front of the quality.
