The manual gives you a good description of the events of the Last War.
It describes clearly the troops, the tactics and the targets of most of the factions involved in the war.
It also considers the roles of the Dragonmarked Houses.
Very useful to give a great Background to your PCs, to create the "War/day-after" mood in your campaign and it also includes a chapter for setting your campaign at different times along the Last War
Not "a must" but very close to it!
