2025 Grief Semi-Flash Exchange

2025-07-15T14:54:08Z

Posted by: glassesofjustice

This is a low-pressure multifandom flash exchange with a Grief/Mourning theme. That does not mean this is a flash specifically about characters dying (but of course, characters dying is on the menu!). Mourning can be the loss of: a loved one, a pet, an object, a character's sense of self, of time, of their past, and more. Grief isn't exclusively or necessarily expressed as sadness, it can be anger, numbness, risk taking, survivors living life to its fullest, etc.

300 words (ship or gen)
art is a competed line sketch
podfic is of a 300 word fic
