Plague's End

Plague's End is the ninth and final quest of the elf series. It is a grandmaster quest and requires completion of Within the Light, Making History and Catapult Construction, in addition to level 75 in ten skills. It has been released prior to Prifddinas, and one of its rewards include access to the city. The Dark Lord, the Iorwerth Clan, King Lathas and the Plague of West Ardougne are plot points dealt with in the quest.

Official description
Lord Iorweth, head of the Iorweth elf clan, has a new plan to summon the Dark Lord, a being with the power to re-grow the elf city of Prifddinas as an Iorweth-only city. Help Arianwyn put a stop to this plot by gathering the elders of Prifddinas and re-growing the city before Iorwerth can.

Walkthrough
To start the quest, you must speak to Arianwyn in eastern Lletya.

Phase 1: Starting the quest
When you speak to Arianwyn, he says that the dwarves have cleared the rock-slide in the Corridor of Light, so we can sneak inside and try to find out what Lord Iorwerth is up to. You'll need to get a set of mourner gear to disguise yourself as a Deathguard, aka Mourner.

Equip the mourner gear and speak to Arianwyn again, and he will teleport with you to the Corridor of Light. If you speak to the Dwarf here, he will give you a Report he found on a dead elf, written by Iestin, who hopes to see Prifddinas restored to its former glory.

Enter the door to the west to a storeroom, then the next door, where the Deathguard captain will demand to know what we were doing in the storeroom. Say that we thought we saw a mouse, and that it might have got into the food stores. We didn't tell you because we knew you were busy. He tells us to relieve the guards in the room to the west, who are guarding the archaeologist Iestin Edern.

Speak to one of the guards, and they will leave. Speak to Iestin and he will ask one of you to take his report to the Mayor of Prifddinas. Arianwyn tells you that you should go while he remains on guard, and you also should try to find out more about Iorwerth's plan. Iestin's report says that he will be able to regrow Prifddinas soon, but he could be able to work faster if he knew the overall plan, particularly what power source Iorwerth intends to use.

Take the stairs to the north, were you will find Starving elves and Mourners. Go north into a building and speak to the Mayor. The Iorwerth master plan is on her desk, but she won't let you look at it. She asks you to check up on her lunch order, a shipment of gnomish foods from Arposandra.

Head south to the gnomecopter, talk to the mourner standing in front of 3 elves, tell him the mayor wants him to distribute the food between everyone. Then go back to the mayor and tell her the food is being distributed by the guards, she will leave and this will give you the ability to take the masterplan. Then head back to Iestin Edern and Arianwyn, give him the masterplan.

Go through all the chat options with him and Arianwyn will tell you to go to Bravek on the first floor of the civic office in West Ardougne, north of the church. And to Councillor Halgrive in East Ardougne.

The Councillor will raise an army but you need to get in control of west-ardougne first, Bravek gives you a list of people to convince to start an uprise: Talk to each of them (Elena being the only one living outside of west ardougne, and they will meet you in the west ardougne church. You must remove your Mourner Gear before you talk to them or they will be un-cooperative. When you've spoken to all of them, go there. In the Chuch, talk to any one of the seven, go through all of the chat options, finally starting the strike! Go to the mourners HQ (North-eastern corner), kick in the door and kill all of the mourners on the ground floor. Continue through the trapdoor. Once downstairs, kill all the mourners and the head mourner. Elena will give you a flag, replace the flag on top of the mourners HQ with it and some knights will arrive. Show them the proclamination from the Councillor and they will go back to the castle. Get some food if you need to and go to the east Ardougne castle, talk to Sir Edmond near the entrance, get up to the throne room and kill Sir Hugo (level 107) guarding the king. Talk to the king and decide to let him live or die. Then go back to Iestin Edern (with either Arianwyn's teleport or the hole near the east gate of Prifddinas.

Iestin Edern will tell you the regrowing the city is the only option to defeat them, and you need to find the Six Lost Elders, go back to Lletya and talk to the scribe about the lost elders.

Phase 2: Find the Six Lost Elders
Gwir will tell you to get a book from the bookcase near her, read it, and then ask her again about the elders, go through all the elder options to get some items. Find them as following:
 * 1) Lady Trahaearn journeyed south from the well. - Enter the Underground Pass from the cave just north of Lletya, run a little east to find a well, then enter through the crumbling wall south of the well. Note: You'll have to climb down the well where you fought iban, then run south and mine the cracked wall if you're running through underground pass. Fight the three level 70 Trahaearn automatons, then repair her exoskeleton with the Rune bar.
 * 2) Lord Crwy's brothers call to him when they are wounded. - Travel to Port Tyras through a charter ship, head north from the Tyras Camp and then a few steps east will be a tree which you can inspect. If you have trouble finding this tree, chop any of the surrounding trees to see a yellow trail leading you to the right one. Inspect this tree and then use the plant cure potion on it and Lord Crwys will appear.
 * 3) Lady Ithell put her soul into her greatest work. - Find five symbols carved into the wood in Lletya. These carvings will teach you how to build a statue in the center of Lletya, using 10 magic logs. Build the statue and Kelyn will talk to you from the balcony. When you speak she'll explain that she has become Lady Ithell. The symbols are located:
 * 4) On the ground floor near the bank.
 * 5) On the first floor on the outside wall north of the altar.
 * 6) On the ground floor on the inside wall of the building east of the archery shop
 * 7) On the first floor of the building in the north-west of Lletya
 * 8) On the ground floor of the archery shop. Poison Wastes Path.png
 * 9) Lord Amlodd sleeps the sleep of the uncalled. - bring the charm you got from the scribe to a summoning obelisk, bring an empty pouch, 1 of each charm(gold, crimson, green and blue) and 200 shards. make the pouch and summon him.
 * 10) Lady Herfin walked westward on the water. - Elf hermit, west of the poison waste (see image). She'll ask you some questions, the correct options are 2,2,1,3.
 * 11) Lady Meilyr brewed a map in the dungeon of the kin. - Talk to Gwir and she'll give you a recipe. Read the recipe and you'll see that you need to add red and blue mushrooms to a 3-dose super defence potion. Go to the Isafdar Hunter Area and pick one of each of the red and blue mushrooms. Grind them and then add the mushrooms to the super defence potion to make a 3-dose meilyr potion. Now head to Daemonheim and drink the meilyr potion. A portal will appear inside the castle (main hall, ground floor) that will take you to Meilyr's home.

Phase 3: Defeat the Dark Lord/Regrow the city
Return to Lletya andhave Arianwyn take you back to the undercity of Prifddinas. Go through a dialogue and agree to go to the Tyras Camp to convince the commander to attack Lord Iowerth's army so you'll be able to perform the ritual undisturbed. He will agree, go back to Arianwyn.

Speak to one of the Elders, they will tell you to enter the library, do so and you'll find the light puzzle. They are quite easy and have to be done 8 times, once for each Elder crystal. Between puzzles, you will also have to fight shadows and greater shadows. (you can safe spot the normal shadows behind the seals) From the third puzzle onward, you will also face the Dark Lord. It is advised to start placing/rotating mirrors from the central receiving crystal to find the correct way much easier. Once the path is complete, activate the crystal and the Dark Lord will attack (again). The fights range from only one shadow with the first crystal, to up to 4 greater shadows and the Dark Lord himself at the last one.
 * Leaving after completing a phase will only restart the last battle you've done, so you can restock if needed
 * The Dark Lord and his Shadows are weak to fire spells, so using magic is recommended over ranged or melee.
 * In addition, he has an area of effect attack not unlike that which Dawn uses, which rapidly harms you for 10% of your maximum life points each hit. Due to the frequency at which he uses this attack, melee is not recommended over ranged or magic.
 * Once you have successfully activated all eight crystals, the Dark Lord will be defeated and the city will start regrowing. Congratulations! Quest complete!

Pre-release
Plague's End was released approximately five years after the previous elf quest, Within the Light. It used to be the top contender for the 200th quest to be released, but the release of the first dragonstone Power to the Players poll in January 2014 changed this. One of the quest design's aims was to create a very long quest. Mod Osborne later stated that he imagined it to take at least as long as Ritual of the Mahjarrat.

After the release of the poll on 13 January 2014 Mod Osborne's Q&A took place, giving more information about the quest. It was revealed that the quest would be released after the release of the first parts of Prifddinas with other story content explaining how the city had been restored from its seed form, although this later changed to completion of the quest being required for the entirety of Prifddinas due to player feedback. It was also confirmed that Seren would not be involved in the quest and would receive separate content at an unspecified later date. Prifddinas and the accompanying quest eventually won the poll, beating the Inventor skill by 14,661 votes.

A month later, Mod John A announced that he had been appointed lead developer for the quest. In a similar way to Birthright of the Dwarves, he would gather ideas and suggestions for the quest on the forums throughout February and March. He also requested suggestions for rewards for the quest, and a ruby Power to the Players poll released in early April established that a new reward would be made for the quest which would not be a crystal halberd, magic staff or thrown weapon. During the quest's development, Mod John A confirmed that the quest would contain a light puzzle.

Mod Osborne later revealed the quest's requirements in a podcast about Prifddinas. A few weeks later, Making History was added as a requirement due to King Lathas' involvement therein. In the official RuneScape video "Spend your Summer with RuneScape", released on 28 May 2014, the quest title "Plague's End" was first mentioned, after which Mod John A confirmed it to be the quest's title. The quest had usually been referred to as "Mourning's Ends Part III" before, which was also one of the titles considered, along with Dark Lord of the Elves, The Gates of Prifddinas and The City and the Seed. According to Mod John A, the title was chosen to reference the first quest in the series, Plague City, and to sound like a finale.

The quest featured in the Behind the Scenes article for August that year, where it was called a "massive milestone for questers" and described as "a sprawling, two-hour+ Grandmaster quest that'll see you start a revolution, complete light puzzles, seek out the lost leaders of the fabled elf clans, and finally come face-to-face with the legendary Dark Lord himself." Another Behind the Scenes video was released the following week, in which it was revealed that the quest would involve Lletya, the undercity of Prifddinas, its Grand Library, the death altar and the Underground Pass, amongst other things.

Trivia

 * Plague's End requires the highest levels in Construction, Dungeoneering, Herblore, Prayer and Summoning of any quest. This also makes it the quest with the highest amount of highest skill requirements.
