Putting Wilhelm Out of Business

Before any of the notes will appear in Naxxramas, you must first obtain and turn in the Omarion's Second Handbook quest. The pages will not spawn until this prerequisite is completed.

In the first room of the Arachnid Quarter, find Omarion's Notes - Pages 3 & 4 inside a broken green pillar on the ground. Omarion's Notes - Pages 5 & 6 are in the tunnel connecting Grand Widow Faerlina to Maexxna, on the right (southern) side between the spider eggs. In Maexxna's Nest, locate the hook point above the entrance, follow the ledge to the right, and pick up Omarion's Notes - Pages 7 & 8 from the ground.

After defeating Grobbulus, before entering the drainage tube leading to Gluth, stand on the pipe and look left — on the ledge above the door next to a grapple point, pick up Omarion's Notes - Pages 9 & 10 from the ground.

Upon entering the Plague Quarter, turn left in the first room and locate the corpse wagon — Omarion's Notes - Pages 17 & 18 are on the spiked wheel at the front of the wagon and blend in with the surroundings. After defeating Noth, go to the green grate in the mushroom hallway and look on top of the largest mushroom in the trio at the back of the grate against the wall to find Omarion's Notes - Pages 19 & 20. Omarion's Notes - Pages 21 & 22 are located directly under the north portcullis in Loatheb's room. Omarion's Notes - Pages 23 & 24 are found on a platform in the same area.

Take all collected notes to Master Craftsman Omarion, who is located inside the altar building at Light's Hope Chapel in the Eastern Plaguelands.
