The Typhoon of Steel

The Typhoon of Steel was the second phase of the Iron War. Arthur Lannister continues his conquest by invading the Marches to punish the Ashfords for their raids into the Stormlands, the Hightowers and Freys enter the war against the Lannisters, and the Iron Islands start raiding once again.

New Entrances
The war in the Stormlands continued as the Hightower/loyalist host marched northward to retake Storm's End from Davos Baratheon. Reginald Hightower has entered the war to gain revenge for Arthur's father, Loren's, murder of his two twin daughters during Loren's War twenty years ago. Reginald has been planning his revenge for some time, and has sent ravens to the Riverlands, to King Ryman Frey. Ryman agrees to enter the war to expand his religion and retake Harrenhal from the Lannisters.

Considering the Frey's the least worrisome threat, Arthur sends his son and heir Tybolt Lannister to lead the defense. Tybolt isn't a warrior or commander, which is why he leads in name only: Lord Patrek Westerling is the true leader of the defense. Arthur sends his favorite and most capable son, Tytos, to put down the Hightower threat.

The Old Way
The Iron Islands had long been ruled by Igon Harlaw, who promoted peace and hope to remove the Old Way and prevent the Iron Islands from getting razed to the ground. He has integrated with the mainland through marriage to Wylla Hightower, Reginald's youngest daughter who avoided death in Loren's War. Igon vows to support his wife's family, and preps the Iron Island ships to raid and plunder the Rock, something they had not done in a century. This creates a renewed interest in the Old Way, led by Urron Farwynd, a mysterious skinchanger who has continued the work of Euron Greyjoy. Urron leads a fleet to "raid the Baratheons"; in actuality he is following Euron's work by heading east to capture priests and mages of all religions.

The Typhoon of Steel
The largest war in over a hundred years had begun. The incredibly skilled Tytos allied himself with King Garlan Tyrell of the Reach by marrying his younger sister Maude Tyrell, and planned to fool the Hightowers by pretending to follow the campaign of his grandfather Loren by sending his troops by sea to land in Hightower territory, while in actuallity the Lannister host will meet up with the Tyrell host in Highgarden then march to Oldtown.
