It had been one year since alastor had been chosen as the sacrifice and headed up the mountain, Rosie sighs before pausing her work at the emporium. She glances around and heads home before changing into hiking gear, "I'm just going to check and see if ... What happened" she tells herself, hoping alastor was alive.

(Every 5 years, a sacrifice at the age of 21 is sent up the mountain and a new 16 year old is chosen to be sacrificed. Rosie escaped this but alastor didn't. She is 29 in this au and one of the few older people who had a sisterly/motherly relationship with him)
