Practical, Countryside, Folksy
Marcher characters live in the mid-west farmlands of the Empire. Farming, hard work and village culture mingle with trade and commerce in this rich agricultural powerhouse.
You're going for an English civil war/morris dancer/English folk sort of feel with the Marchers.
Autumn Harvest Palette
Natural dye colours, plain blocks of colour, in linen and wool. Sort of Autumnal in theme.
