Overview
The Battle of Hengzhou was the shaper assault that devastated Hengzhou, the capital of Hengvaris, after the shapers of Shroudvale broke free. The shaper attack on Hengzhou leaves Vianna believing her family is gone, brings her into Khoradyn and Garrik's army, and sends Hengzhou survivors east with the army that later founds Kaldaryn.
Course
Vianna, Marcus, Vivian, and Julian are living in Hengzhou after fleeing Brighthaven when the shapers attack. Vivian orders Vianna to hide. The rest of the family goes out to fight. When Vianna emerges, much of the city has been reduced to wreckage, with streets broken by rubble, smoke-darkened stone, fires, fissures, and destructive magic.
Isaac has already asked Garrik to steer Khoradyn's army toward Hengzhou because Vianna is there. Malcairn also reaches the army with news that Shroudvale is attacking Hengvaris. Khoradyn sends Kren ahead with an elite detachment, then speeds the main army toward the city.
By the time Khoradyn's force arrives, Hengzhou's defenders are already collapsing. Khoradyn leads the counterattack with earth magic. Kren and Zhang fight at the front. Garrik and Isaac focus on shielding, healing, clearing debris, and finding survivors as the army drives the shapers back.
Aftermath
Garrik, Khoradyn, Kren, and Zhang find Vianna among the survivors. After the loss of her family, she attempts suicide; Garrik heals her, and Kren keeps watch over her afterward.
The survivors who follow Khoradyn and Garrik march east with the army that founds Kaldaryn. The Great Shaper War then moves toward Laizhou, where the army from Hengzhou joins Laizhou troops for a decisive clash. By 5368 AX, Hengzhou is active again. Its outskirts still show scars from the shaper attack on Hengzhou and regrowth where areas were once razed.
