—Narration of the Yied Massacre in the Opening of Thracia 776
After the massacre, Travant took Altena and the Gáe Bolg back to Thracia, leaving Magorn to lead the remaining dragon knights in battle against Sigurd's troops.
With Leonster's army largely decimated and the loss of the Gáe Bolg, Thracia seizes the chance to launch an invasion of the Manster District, starting with Manster itself. After defeating the defending King Calf of Leonster's remaining forces at the Battle of River Thracia, Thracia then attacks Leonster Castle, sets it ablaze, and for a short time, Thracia takes control of the Manster District. However, Grannvale, now under control of Arvis after his victory at the Battle of Belhalla, invades Manster (with one of the victims being Grahnye, Eldigan's widow and Ares' mother) and forces Thracia to sign a treaty which annexed it as a territory of Grannvale. Arvis then installs Duke Bloom of Freege as its new king. As a favor to Raydrik for his role in Leonster's downfall, King Bloom makes him the Duke of Manster.
During all this, Quan and Ethlyn's son Prince Leif manages to evade the new Grannvale Empire's forces that are trying to capture him, thanks to the efforts of Quan's loyal pupil and retainer Finn, among others. Around a decade later, Leif would be reunited with his sister Altena (now the Princess of Thracia and one of Travant's lieutenants), convincing her to join their cousin Seliph's Liberation Army.
In Thracia 776, it is revealed that Manfroy and Veld manipulated Travant into carrying out the Yied Massacre.
