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 ring, 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 telepathetically 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.

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. Enter the northern room to do battle with 8 wights in waves of 1 wight, then 2 ranger wights, then 5 wights. 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.

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.
