Firefly Tart is a traditional food from the undergas of Zeelich.
When Twinsen visits the Village of the Wannies, he tastes the tart and saves a slice. Then he finds out that the tart is made of fireflies and passes out.[1] Later, he needs to give the slice to the old man in in the village to get the key to Dark Monk's chapel.[2]
