The Second War of the Dragonborn

The Second War of the Dragonborn followed the First War of the Dragonborn, and was largely driven by the same two races: the Dragonborn of Darvekon and the humans of Agrarnon. However, both the dwarves and the elves were drawn into this conflict, eventually turning the tide of the war against the Dragonborn and driving them back to Darvekon.

The war was begun by the Dragonborn attacking Killmark at both the southern and southeaster-most tips of Agragnon simultaneously, largely in an attempt to surprise the humans and capture (and likely murder) the royal family. When plots against the royal family failed, the Dragonborn continued their dual assault in force, eventually overtaking much of Killmark and pushing into Lanáun. (The Duchy of Templemore did not yet exist.)

Both the dwarves of the Pierced Mountains and the Elves from the Shining Forest were eventually drawn into the battle, largely in defense of Agrarnon and (in the case of the elves) out of loyalty to King Thomas the Good. The three races overwhelmed the Dragonborn before the elves returned to the Shining Forest due to strained relations with King Thomas and the human forces. The end of the war and increased concerns over a third war with the Dragonborn resulted in the formation of the female-led Agrarnon Protectorate, the Duchy of Templemore, and the establishment of abbeys throughout Agrarnon.
