After reading the Comic and learning of the Spirit of Slumber, this is what you have to do.

Step 1:

Return to the Elephante, and click on Go to the Path.
It will bring you to Neovia.



Click on the burned house in Neovia. (left bottom corner, a bottle like building)

(Note: go to the bottom of this post and see this exact same map that's numbered 1. )

It will bring you to this page:



Now you have to find the locket. Try to go to the following place and click on it. I think it's random because sometimes I have to click certain places many times and I finally found in under the sofa.

1. Fireplace
2. Sofa
3. Shelf
4. Stairs
5. Under the Stairs
6. Wood Pieces
7. Red Pillow
8. Table Leg
9. Under the Couch
10. Chair

If you click correctly but haven't found the locket, you will see an image like this:


If you didn't click correctly, you will see an image like this:


So be careful how you click at these area. When you finally find the locket, you will see an image like this:



Step 2

You have to talk to a few people. Go to the 4 places below and either refresh or play the game or buy a scratchcard. I refresh a lot of time and the conversation doesn't come up. Finally I play a game at bagatelle and when I went to Cork Gun Gallery, the conversation started. Below are my conversation:

a. Cork Gun Gallery


b. Bagatelle



c. Coconut Shy



d. Halloween Scratch Cards


The conversation will be at the bottom of the page.

The advise is that you go through these people according to these conversation:

1. Certainly, miss...
2. I haven't seen such metalwork in...
3. That piece of junk?
4. It looks familiar

Check who say which of the above conversation, and go to talk to them in that order.

When you do the right steps, you will see Gilly say this:



Step 3:
Once you saw Gilly said nobody will help her, go back to the Neovia.Go to the building on the left bottom corner. Somewhere behind the building, when your cursor becomes clickable, click there and it will bring you to the spooky shack.



Spooky Shack



And so you have finished and we wait.

NOTE: IN THE LAST MAP OF NEOPIA, I INDICATE 4 WHERE IT WILL LEAD YOU TO SPOOKY SHACK. THE NUMBER 4 SHUOLD BE NUMBER 3. (I am too lazy to go back to change this. May do it later. LOL.)
