You will have a choice between two sides in this quest. You can either choose to help Ceril Carnillean get his family armour back and foil the plan to revive Hazeel, or you can choose to help Hazeel's followers murder a Carnillean and resurrect their master. Siding with Ceril can be considered the "good" choice, while resurrecting Hazeel can be viewed as the "evil" choice.
