Gull-koo loves her briar hearts! She's an interesting old bird, that hagraven. Since coming to the old Breton fort, my job among the Winterborn has been to assist Gull-koo, doing whatever the hagraven needs in order to make sure the briar hearts grow and thrive. Strange things, those briar hearts. Kind of like large fruits, but also kind of like the heart of some large animal. Or man. Your sister, writing from Frostbreak Fortress
