Description	This chapter of the quest takes our hero deep under the mountains of Arandar to put a stop to the evil plans of the mourners. If our hero is to succeed, they must solve one of the most complicated puzzles in all of Gielinor.
Requirements	Completion of the following quests: Mourning's End Part I Roving Elves Regicide Underground Pass Biohazard Plague City Waterfall Quest Big Chompy Bird Hunting Sheep Herder
Items required	Full mourner clothes A chisel (one can be found in the house south of the Mourner HQ) A death talisman/tiara, catalytic talisman/tiara, Runecraft cape or 50 junk items Rope
Recommended	65+ Combat level 75+ Agility for lesser chances of failing obstacles (91 to never fail)^[1] 43+ Prayer for Protect from Melee against the shadows Teleports to West Ardougne: Minigames teleport to Rat Pits (Ardougne) available every 20 minutes after completion of Ratcatchers quest West Ardougne Teleport or its tablet Ardougne Teleport or its tablet A teleport crystal Lots of food, prayer potions (20 doses at 61 prayer), and stamina potions (12+ doses). Summer pies provide an excellent source of food, since they boost 5 Agility levels, restore 10% run energy, and give 22 health per pie. Alternatively, stackable purple sweets, which restore 10% run energy and 2 health, may be used. An explorer's ring can be brought along as well, which can restore 50% run energy, twice a day. (Note: If using protection prayers in the temple, food will only be needed for the agility obstacle in the first and fifth puzzles) High Prayer bonus armour (e.g. proselyte or initiate armour, a god book, a holy symbol or dragonbone necklace or bonecrusher necklace, a god blessing, a broodoo shield). A melee weapon that provides a Prayer bonus, such as any mace, Godsword, Zamorakian hasta, ancient mace, silver sickle (b), crozier, dragon mace, Void Knight mace, the Ivandis flail, blisterwood flail, or Wolfbane. The ancient mace's special attack can be useful as it refills prayer points. The Ivandis and blisterwood flails weigh 0 kg. One pure essence to craft a Death rune once in the Death Altar at the end of the quest (requires 65 Runecraft ^[boostable], needed for hard Ardougne Diary), can be done easier via the Abyss later but might save time for Ultimate or Hardcore Ironmen
Enemies to defeat	None (but powerful level 73 shadows are aggressive to players inside the temple)
Ironman concerns	A method of reaching the Death Altar at the end of the quest: Handing in 50 junk items during the quest for a death talisman OR 90 Slayer to kill dark beasts for a death talisman OR Completion of Temple of the Eye to be able to participate in Guardians of the Rift, where a catalytic talisman may be obtained randomly from the rewards guardian
League notes	Unlocking Tirannwn✓ will auto-complete the quest

Items recommended: Elf teleport crystal, teleport to Ardougne, food and armour/prayer potions to run past high level monsters, 3 free inventory spaces

Map of the area and path to the blackened crystal.

Talk to Arianwyn in Lletya.
(optional) Note to Ironmen: if you do not have a death talisman, search the bookshelves for a book titled Prifddinas' history. You might need it later as part of the 50 items and this will allow you to potentially save time and a charge on your teleport.
