The Sisters of Sisterton is a roving patchwork of women from across all of Westeros. They fervently reject patriarchy and zealously strive to establish a community ruled by and made up of entirely women.
The Sisters of Sisterton adhere to naturalist tendencies, preferring to live off the land while respecting nature. The travel where they wish where they live in temporary campsites which can be dismantled immediately if necessary.
The Sisters have embraced a version of egalitarianism that rejects displays of opulence and extreme wealth, which they view as a means of classist suppression. Accordingly, they make it a mission to redistribute wealth as they see fit, taking from corrupt and rich lords and giving, often by anonymous means, to the poor masses.
