edit Introduction
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 (the good side), or you can choose to help Hazeel's followers murder a Carnillean and resurrect their master (the bad side). Butler Jones, a Cult of Hazeel member, plays a part in both sides, having replaced Higson when he disappeared.
edit Walkthrough for the Cerils' side
From Ceril's house, walk south and cross the bridge. Go past the clock tower, then go east until you find a cave. Enter it. Talk to Clivet to learn about Hazeel, an ancient and powerful follower of Zamorak who was killed by an ancestor of Ceril. He will ask for your help in reviving Hazeel. Refuse.
Clivet will sail away on a raft, saying that you'll never be able to find him. You need to find five Sewer valves and turn them the proper direction.
Valve 1 - This is right across the bridge south of the Carnilleans' house. Turn it right.
Valve 2 - This is right behind Carnilleans' house. Turn it right.
Valve 3 - This is north of the cave. Turn it left.
Valve 4 - This is south of the zoo's penguin cage. Turn it right.
Valve 5 - Go southeast of the fourth valve, past the monk. Turn it right.

Fighting Alomone.
After you've turned all five, go back into the cave and take the raft to the cult's hideout. If Clivet is still next to raft when you return, kill him. Almone will not appear in the hideout if clivet is by the cave entrance. Talk to Alomone (he's the one who does NOT have a staff). He will tell you that the Carnilleans' butler should have killed you by now. He will then attack you, he's level 13. Kill him to get the Carnillean armour.
Take this to Ceril Carnillean. He will not believe you about Butler Jones. Go to the first floor and talk to him again. He will take the armour but still deny the accusations against Jones. He will give you a reward. Well, sort of.
