Are these three sentences worded in the best way?

In 1344 DR, when Dorn was nine, he and his parents were sent with a merchant caravan traveling to Yulash, but their party was attacked by a red dragon during the journey. The wyrm killed both Dorn’s parents and tore off his left limbs (and much of the surrounding flesh) before leaving him to die. The wizard who owned him and his parents transported to the site a few moments later to retrieve whatever remained of his property.
