Missing, Presumed Death

Missing, Presumed Death is a quest that features Death, who has gone missing, and the Menaphite god of the dead Icthlarin, who is attempting to take over his role until he is found. The quest starts in Silvarea, west of Paterdomus, where some monks have been murdered, their souls unable to pass on due to Death's disappearance.

It also involves the Mahjarrat Sliske, revealing how he obtained the Staff of Armadyl from the Dragonkin prior to the assassination of Guthix.

Murders in Silvarea
To start the quest, speak to Brother Samwell in the mountain pass of Silvarea, located west of Paterdomus and east of Varrock.

Investigate the slaughtered monks, tree with an arrow stuck in it and the nearby plant to find all the core clues. Talk to the south west slaughtered monk to gain an additional clue. Return to Brother Samwell.

He will then say find a witness, Go up the hill and talk to the odd old man. In order to get him to talk, persuade him three times, then threaten him. Return to Brother Samwell.

Next, follow the crystals to the east, and search the dead elf to find a core clue on his hands and an additional clue by listening to his soul. Also investigate the plant to find a necklace, the clothing on the fence, and the bench to find a letter. Talk to Blaze by threatening him twice then persuading at the beacon for more information, then return back to Brother Samwell.

Go to the Wizard's Tower south of Draynor and talk to Wizard Valina. Show her the clues, then ask her about elves, Saradominist wizards and teleportation. Accuse her of covering up for wizards for a more thorough explanation. She will claim that it is neither elves or wizards who did the crime.

Return to Brother Samwell and tell him what was learned. Icthlarin will communicate with the player telepathically and appear. Go through all his dialogue options to learn about Death's disappearance and their work. At this point, 4 wights will attack. Icthlarin can weaken them but he cannot finish them off.

After defeating the wights, one of them will drop an invitation box. The box, left by the killer Sliske, will invite Icthlarin to attend his ascension. Ichthlarin will debate going but decides to do so after dealing with the dead monks. Open the invitation box to be transported to the Empyrean Citadel.

The Empyrean Citadel
Upon arriving at the citadel, there will be representatives of the gods standing outside a set of doors guarded by the Barrows Brothers. Commander Zilyana will be arguing with Ilfeen over the murders. Telling them the truth will result in Ilfeen trying to make peace but Zilyana rejecting it. Talk to the others gathered there to learn more about their gods and activities. Talk to Icthlarin to proceed.

The Maze
Enter the door to the west then head north to the window to witness a cutscene of Saradomin, Zamorak, Bandos and Armadyl arguing while Brassica Prime remains silent. Icthlarin enters and tries to unite them to no avail. Once the cutscene is over head round the crates and out the southern window, jumping over the gap, running over the planks, jumping down the rocks then up the rocks to enter the western window. Climb over an obstacle then head to the northern door to proceed.

Attack of the Wights
Enter the northern room to do battle with 7 wights in waves of 1 wight, then 2 ranger wights, then 4 wight footsoldiers. In order to damage the wights pull the levers to reveal light then lure the wights into the light. Once all the waves are dead go to the window to view a cutscene of the gods discussing why they are here, then go through the door to the north.

Shadow Caster Puzzle
In this section, you will encounter a room with two masks on a viewing panel. Clicking on the panel will yield an interface in which you need to rotate the shadow casters to project an image on the floor. Rotate the bottom-left machine once, the top-left one twice, the top-right one three times and the bottom-right machine once. This will form the correct shape from the shadows. Go to the window to view a cutscene of Sliske's arrival.

Riddle Puzzle
After solving the last riddle, you will receive an invitation to Sliske's ascension. Go to the window to see Sliske summon Death and the Dragonkin Strisath. Leave by the southern door and jump off the roof.

On the edge of war
Speak to one of the Barrows brothers to get inside the main room. Once inside Sliske announces a contest: whoever kills the most gods, will be awarded the Stone of Jas. After a lot of commotion to trust Sliske or not he sets the dragonkin loose (which goes on a rampage) and throws the key to Death's cage at you. Icthlarin will put on a shield to protect you from the dragonkins attacks while you must get to Death. To get to Death, head west and stamp out the flames until you get to his cage. Free him and return to Icthlarin where a cutscene will play and Death will teleport everybody remaining to safety.

Note: if you or Icthlarin, after his shield fails, get hit by the Dragonkin's attack you must start the whole sequence again.

Trivia

 * The quest's title is a pun on the classification "missing, presumed dead" used for people who have been missing and are most likely to have died.
 * It is possible that Zaros was present in his spirit form on the event of Sliske's Ascension. A purple aura could be seen over his podium, whereas for other Gods who were not present such as Seren, Marimbo and obviously Guthix, no such aura appeared. It's also possible that this aura was not his spiritual form, but just an indication that his attention was turned towards the event. Given that he is currently apparently on another world, the latter may be more likely.
 * This quest marks the first time the gods Armadyl and Bandos are seen.
 * If the player sides with Zaros in the Citadel meeting room, a dialogue box appears that states the player feels a strange presence around them.
 * Upon completion of the quest the Adventure's Log states: I saved Death from Sliske, after hearing him announce that he would give the Stone of Jas to the person that could kill the most gods.
 * The outcome from The World Wakes, along with who you sided in the Battle of Lumbridge are included in this quest.
 * Even after the completion of the quest, Brassica Prime will still be inside the room where all the gods were.
 * The talking masks in the first puzzle room will occasionally say things that breaks the fourth wall, such as referring the puzzle as novice difficulty or accusing the player of using a walkthrough and amongst others.
 * Relomia, the Emissary of Sliske, can be seen on the walkway to the second puzzle room on one of the floating rocks in the distance. She seems to have arrived to see Sliske.
 * Near the Memorial Statue there is storage crate. Investigating this crate reveals that it contains several copies of a list. The list mentions the gods invited to the ascension, and states that death and the player are mischief-makers.
