Is this paragraph worded correctly? Also, for the last sentence, is it clear that the quarry/the undead marauders killed the villagers? About two months later, Aoth Fezim, a war mage and the captain of the Griffon Legion of Pyarados, and his griffon familiar, Brightwing, hunted undead creatures that Szass Tam’s followers had sent to raid the countryside of Pyarados. They were accompanied by one of the Griffon Legion’s officers, the bard and warrior Bareris Anskuld; Mirror, the ghost of a paladin; and Malark Springhill, a Monk of the Long Death and the spymaster to Dmitra Flass, the governor of Eltabbar and the zulkir of the Order of Illusion since Szass Tam had killed her predecessor. When the companions tracked their quarry to a small village where the inhabitants had been slaughtered, they engaged and destroyed the undead marauders, a group of skeleton warriors and a colossal bone serpent.
