Prompt: Frost
The first hard frost of the year really rammed home the notion that the group needed to find a permanent shelter and base of operations for the winter. It was difficult to travel in the extreme temperatures, and food and other basic supplies would become much harder to come by, especially for the now much larger group. The only advantage was that most other dark guilds that were mobile would also hunker down for the winter, making them a little easier to pick off once located.
Erza had volunteered to procure anything the guild required from towns herself, but somehow it didn't quite sit well with Macbeth that she continually used her own funds on their wellbeing. Made him feel like he owed her to a degree, which was simply unacceptable.
