Wesnoth is under assault from horrors from the north and lands beyond. Sequel (and conclusion) to Bad Moon Rising, though it can be played on its own.
SP Campaign, complete but there may be some bugs, and some revision may be needed (based on feedback). The last half has been massively revised from the version available in BfW 1.10; the campaign has been split into two campaigns. Requires the add-ons Archaic_Era and Archaic_Resources.
