Start by talking to Leela between the Draynor Village jail and wheat field. She will ask you go to a flat-topped pyramid near Uzer, and speak to the local mummy buried there.
Travel to the desert, and head to the area marked on the map below.
Enter the pyramid from the front door. Study all the items on the ground, and rummage all of the skeletons. The skeletons will animate and attack you. Kill them. Some of them will drop a, journal, scroll, mummy hand, and canopic jar.
After killing all of the skeleton looters, getting all the items, and investigating all the AMCE products, return to Leela. Tell and show her what you found, then return to the pyramid.
Golems, Scarabs, & Mummies (Oh my!)
Return to the western room on the first floor. Try talking to the golem near the stairs. Kill the golem. Note: Only crush typed weapons can damage the golem! If you don't have a crush weapon, just punch/kick it with no weapons equipped.
Head down the stairs then grab the canopic jar to the west. Go east the grab the jar to the northeast. Go south now and pick up the mummy and other canopic jar. For a future shortcut, enter the uninviting hole near the last jar and enter the other hole just to the south of it. Enough rubble will be cleared so that you can now use it as a shortcut.
Return back to where you found the canopic jar (can use the hole now!), then head south of the stairs. You will see a very large grid. To cross safely, you can only step between Yellow and Red tiles, or Blue and Green.
If you try going from red to blue, or green to yellow (as two examples), you will take a high amount of damage.
Use the mummy hand onto the mummy body. Then click to fill the sarcophagus. Now place the four canopic jars on the west side of the chamber.
Use the grain on the empty pot, and replace the broken pot on the east side of the sarcophagus. Use the spice on the jug of wine, and replaced the broken jug nearby.
Repair the broken chair on the west side of the sarcophagus. Repair the broken table too. There's one other thing you can do for the body double, but we'll get back to that later.
Pray at each of the broken statutes to repair them. After all of them are completed, you can then pray at any of them. The Amascut statute has the chance to restore over your prayer level, at the cost of some life points.
Now head into the room to the east. You will see Tumeken's shadow wandering around. Kill it. There are four enchanted sconces around the room. Light the south one, and Tumeken's shadow will appear again, this time stronger. Kill it, then light the north one. Repeat, then light the east, followed by west.
Senliten, the Pharaoh Queen, is now 75% completed. Speak to the Queen and ask what you want to know. When ready, you can return to Leela to complete the quest, or you can continue on for 100% completion. 100% completion earns more experience and is required for The Curse of Arrav and Do No Evil.
Towards the southeast corner of her sarcophagus, begin a statute of the queen. Carve it further two more times. For her name and personality, travel to Al Kharid. To the far north, north of the Scorpion Mine, look for the boy handing out leaflets and advertising. Take a leaflet from him.
Now, go to Ali Morrisane.
Question him about a tomb. Tell him you're looking to reunite the mummy. He will tell you that he sold Reldo some documents that will help with her personality, but he can help you with the name. But for the name, he wants a glass of sq'irk juice.
Head to the Sorceress's Garden by speaking to her apprentice.
You can get any sq'irk juice you want. If you need a beer glass, search the shelves in the house. Once you have enough sq'irks, use a pestle and mortar on them to get the juice.
Return to Ali M, and talk to him about the mummy again. He will give you the copy of the documents in exchange for the juice. Make sure your ring of charos (a) is equipped, then talk to him again about the mummy, and he says he will part with the original, for a fee. You will persuade him to give you the original for free.
Now go to Reldo in the Varrock Palace library.
Talk to him about a pyramid. Using the flier, he will check his copies of the original. They will be correct, and will give you the original. Return to the Queen and talk to her. You will give her the documents reminding her of her name and personality.
She is now at 100% completion!
