The First War of the Dragonborn

The First War of the Dragonborn took place primarily between the Dragonborn of the newly-claimed island of Darvekon and the humans of Agranon.

The war was won by the Dragonborn after King Simon the Third (the Weeping King) retreated from his leadership role after the death of both his son (Prince Sebastian the Valiant) and daughter (Princess Loria) on the same day. King Simon was never the same, and the humans were defeated in spirit when his courage faltered.

On the heels of the humans' retreat, the Dragonborn counter-attacked Agranon, but dwarves from the Pierced Mountains marched south and repelled the Dragonborn's attack. Shortly after this defense of the mainland, the Dragonborn and humans settled into an uneasy stalemate, with the Winged Channel serving as a water-based border between the two races' homelands.

Timeline
Following are the major events of the First War of the Dragonborn:
 * 1359 CD: The humans of Killmark North and Lanáun cross the Winged Channel and attack the Dragonborn, attempting to reclaim the island of Darvekon for Agrarnon and its king, Simon the Third (later known as the Weeping King). This siege is considered the first attack in the war.
 * 1360 CD: As the Dragonborn of Darvekon begin a systematic defense and slaughter of the oncoming humans of Agrarnon, King Simon officially declares war on Darvekon. Humans from the provinces throughout Agragnon are called into service and begin crossing the Winged Channel in force to attack Darvekon.
 * 1362 CD: Three years into the First War of the Dragonborn, King Simon's oldest son and general of the human forces, Prince Sebastian the Valiant, is struck down in battle on the same day that a Dragonborn assassin murders King Simon's eldest daughter, Princess Loria, on her 13th birthday celebration. King Simon retreats into his castle and never leaves it again.
 * 1363 CD: King Simon remains in his castle, and is often seen weeping out the window of Princess Loria's tower room. He refuses to command his armies, and his dukes begin calling back their countrymen from the shores of Darvekon. The armies of men despair and begin to suffer catastrophic casualties. The war is considered lost to the Dragonborn.
 * 1364 CD: The Dragonborn, flush with power and overwhelming numbers, cross the Winged Channel and attack the southwast coast of Agrarnon. The dwarves of the Pierced Mountains to the northwest march in force and dispel the Dragonborn armies. Darvekon and Agrarnon settle into an uneasy peace for nearly one hundred and fifty years, until the Second War of the Dragonborn.
