Byron Howe is first mentioned when he attends the Orlesian King Meghren's birthday in the Royal Palace along with the rest of the Fereldan nobility. These celebrations took place not longer after Queen Moira Theirin's death at the hands of Bann Ceorlic. Byron presented the king with a dwarven-made sword as a gift. According to him it was given for the first of his line by a dwarven king. Meghren seemingly took offense that this gift was not made for him. Grand Cleric Bronach intervened and the blade was donated to the Chantry instead but not long before Meghren ridiculed Byron a bit more, in front of the entire Fereldan nobility.^[3]

After the Battle of Southron Hills, the rebel army led by Prince Maric Theirin sustained heavy losses. For many months the rebels camped in remote areas in order to escape the loyalist forces as well as recruit more Fereldans and regain their power. In one occasion, the rebel army camped in the lands of Amaranthine. Arl Byron Howe ignored their presence and quietly let them know that he would allow them to stay there.^[4] However, the rebels stayed for several months making their position well-known to the locals. This drew attention and eventually the Orlesians learned about it and sent a large force to defeat them. Byron Howe was informed of this development so he sent a messenger to the rebel camp to inform them.^[5]

Maric was impressed a lot by his action so before he left along with the rest of the rebels, he took Loghain Mac Tir with him and visited the Arl in his estate of Vigil's Keep. The conversation was very short in which Maric thanked Byron for his help and Byron saying that it was the least he could do. Unexpectedly, the next day the rebel army encountered a force of Amaranthine soldiers led by Byron. The Arl said with thick voice that he sent his family to the north and brought with him all his loyal troops and what supplies he could gather.^[6]

For the next two years Byron Howe stayed with the rebel force which was becoming larger but real battles were sporadic. Eventually in 8:99 Blessed it was decided the rebels to hit Gwaren which was a remote town with few soldiers to defend it, as most of them were given to King Meghren. Arl Byron was tasked along with his men to raid in western regions in order to provide a distraction to the loyalist forces while the rebel army marched on Gwaren.^[7] Byron was successful in his distraction, but eventually a full legion of chevaliers accompanied by Circle mages destroyed them. Before they were overrun however, Byron wrote a letter in order to inform the rest of the rebels of what happened. According to Katriel she was supposedly the messenger. Katriel arrived in Gwaren during its sacking by the rebels and according to her, Byron Howe died four days ago.^[8][9]
