As part of this chapter, you'll unlock permanent access to a new location: the duchy of Burgundy, a medieval city translated into the Neath. Ride out in a hunting party, pursue the dreams of kings, politic with the ducal court and uncover the secrets concealed beneath the gold and glory. Not all that glitters…
