Starting the quest

 * 1) To begin, go to East Ardougne and talk to Elena in the house just east of the house where the Plague City quest begins.
 * 2) She will tell the player about how she was able to collect some good samples of the plague, but unfortunately the Mourners took all of her equipment.
 * 3) She now needs someone to sneak back in to try to find it. She suggests that the player should go talk to Jerico, since the tunnel used to get in before has been sealed off.

Getting into West Ardougne

 * 1) Jerico lives in a house just south of the northern bank in Ardougne and just north of the church.
 * 2) He tells the player that he has arranged for Omart to help create a rope ladder to get over the wall. He will tell the player to go find Omart.
 * 3) Search the cupboard nearby to find some bird feed and grab a pigeon cage from the back yard before you go.
 * 4) Omart is found west of Ceril Carnillean's house in East Ardougne, just south of the castle. He is located outside of the south-east corner of West Ardougne's walls. He will tell you to talk to Jerico but this step is not necessary if you retrieved the bird cage and bird feed already.
 * 5) Now head to the watchtower, directly north of Omart. Stand in the corner where the two spiked fences meet and use the bird feed on the watchtower fence.
 * 6) Next, open the pigeon cage to release the pigeons. They'll immediately fly into the tower to eat the feed. This will distract the guards.
 * 7) Go south to Omart and talk to him. He'll help the player get over the wall.

Finding the Mourner Headquarters

 * 1) Head to Martha Rehnison's house first used in Plague City. It is located to the north of the dungeon in the middle of West Ardougne.
 * 2) Pick up the Rotten apple on the east side of the house.
 * 3) Squeeze through the fence to the east. The player is now in the back yard of the headquarters.
 * 4) Right-click to use the rotten apple on the cauldron. Accidentally eating the rotten apple does not cause damage.
 * 5) Squeeze back through the fence and walk around to the front of the building, and attempt to go inside. The player will not be allowed in because several mourners are ill with food poisoning, and they are waiting for a doctor.

Using a medical disguise

 * 1) Head to Nurse Sarah, who is in the large building south-west of the West-Ardougne church.
 * 2) Search the box in her house to obtain a doctor's gown. Players can obtain two by using the drop trick.
 * 3) Equip the gown and go back to the headquarters. The medical professional attire will allow the player to enter freely. The gown must be equipped each time the player needs to enter the headquarters.

Infiltrating the headquarters

 * 1) Go upstairs and kill a Mourner (level 13) while still wearing the doctor's gown. A key will automatically be placed in the player's inventory.
 * 2) Use the key on the gate to get inside the room.
 * 3) Search the crates to find Elena's distillator.
 * 4) Exit the Mourner Headquarters.
 * 5) Head back to Omart at the south-east corner of West Ardougne. Kilron will help the player get back over into East Ardougne. Alternatively, players can head through the sewers because they are no longer blocked.
 * 6) Go to Elena and give her the distillator.

Obtaining the samples

 * 1) Elena will extract a sample of the plague, but the results of her test are strange. In order to get further results, she needs some help.
 * 2) Elena will give the player a plague sample, liquid honey, sulphuric broline, and ethenea.
 * 3) The samples will need to be taken to the chemist in the western-most building in Rimmington to get some touch paper. Then the samples and paper need to be taken to Elena's mentor, Guidor, in Varrock.
 * 4) Before going further, read the next section completely.

Traveling to the chemist

 * Be extremely careful in the next few sections! Read the steps ahead of time. They require lengthy walks, and errors can drastically increase the time it takes to complete the quest.

The plague sample is extremely fragile! Any of the following will cause the sample to break. Any of the following will not cause the sample to break.
 * Teleport spells
 * Teleport tablets
 * Teleport house portals
 * Spirit trees
 * Teleportation jewellery (Amulet of glory, Ring of dueling)
 * Skull sceptre teleport
 * Cabbage port
 * Clan Vexillum Teleport
 * Any combat
 * Charter ships
 * Fairy Ring teleporting
 * Failing agility shortcuts
 * Balloon transport system

Note: If any of the samples break, players can get them replaced by talking to Elena. It might be wise to use the Drop trick to get a second set from Elena. The extra set can be banked. This prevents the need for a trip back to Ardougne in case of an accident.

Rimmington method 1

 * Requires any quick teleportation method to Falador or Draynor Village.


 * 1) First, walk the four samples to the north bank in Ardougne and deposit them.
 * 2) Teleport to Falador (or Draynor Village) using any transportation method.
 * 3) Withdraw the samples from the bank and walk to the chemist in Rimmington.

Rimmington method 2

 * May require up to 1600 coins.


 * 1) Walk the four samples to the pier located in the southeastern part of East Ardougne.
 * 2) Sail to Brimhaven for 30 coins.
 * 3) Charter a ship to Port Sarim. OR Walk to the banana plantation to sail to Port Sarim for 30 coins.
 * 4) Walk to the chemist in Rimmington.

Rimmington method 3

 * Requires access to the fairy ring network.


 * 1) Walk the four samples to the fairy ring located near the Tower of Life located south of East Ardougne.
 * 2) Use the ring to teleport to Zanaris.
 * 3) Use the fairy ring code AIQ to teleport to Mudskipper's Point.
 * 4) Walk to the chemist in Rimmington.

Obtaining the touch paper

 * 1) Go inside the chemist's house which is located on the west side of town.
 * 2) Talk to him with the four items in your inventory. Say that Elena needs some touch paper for Guidor. DO NOT mention the plague sample or else he will take it away.
 * 3) The chemist will give the player touch paper.

Smuggling the samples

 * 1) Ask the chemist if he has any ideas on how to get the samples past the guards in Varrock.
 * 2) The chemist will suggest giving a vial to each of his three helpers: Chancy, Da Vinci, and Hops. They are located right outside the chemist's house crowding around a fire.
 * 3) Give Chancy the liquid honey.
 * 4) Give Da Vinci the ethenea.
 * 5) Give Hops the sulphuric broline.

Note: There are a few solutions if the wrong vials are used. Remember not to break the vials. The easiest solution is to withdraw the second set from a nearby bank if you used the drop trick earlier. Another option is to simply return to Elena for another set. The last option is to travel to Varrock and speak to the three helpers in the Dancing Donkey Inn without carrying the plague sample. The guards will confiscate the plague sample because the Inn is located in the fenced off area east of the east bank in Varrock. The helpers will return the vials to the player. With the extra vials, the player must go back to the chemist's house in Rimmington and correct whatever mistake was made.

Method 1

 * Requires any transportation to Varrock.


 * 1) Walk to Falador or Draynor Village bank. Or deposit box in Port Sarim.
 * 2) Bank the plague sample and touch paper.
 * 3) Travel to Varrock using any transportation method.
 * 4) Withdraw the plague sample and touch paper from the east bank.

Method 2

 * Requires access to the balloon transport system and a willow log.


 * 1) Walk north to the hot air balloon near the crafting guild.
 * 2) Use the willow log to travel to Varrock.
 * 3) Walk southwest to enter the city.

Preparations

 * 1) Buy both parts of the Priest gown from Thessalia's Fine Clothes located on the west side of Varrock square for 10 coins. These are NOT the same as Monk's robes! There is also a clothing store next to Guidor's house in case the player forgets.
 * 2) Next, go to the south-east part of Varrock where two guards are in front of a gate.
 * 3) Try to use the gate. The guard will search the player, but he won't find the plague sample. Use the gate again, and the player will be allowed to pass.
 * Now, head to the Dancing Donkey Inn (marked with a [[File:Beericon.PNG]] on the minimap) and talk to the chemist's assistants to get the vials back. Your inventory MUST have space for the three vials. Having a full inventory will require you to obtain a new set from Elena.

Note: The guard does not check players leaving the area, but does when they attempt to enter. There are ways to leave the area and get back inside without the guard confiscating the samples. Players can use the Telekinetic Grab spell by dropping the vials before entering the gated area and then casting the spell from inside the gate. If the spell is too high of a level, drop the vials inside the gate before leaving. Players have two minutes to run to the bank and return before the items disappear.

Guidor's house

 * 1) Equip the priest gown.
 * 2) Head to Guidor's house in the south-east corner of the gated area. Attempt to enter.
 * 3) Guidor's wife will only let the player through while wearing the robes.
 * 4) Talk to Guidor and give him the vials and sample.
 * 5) After analysing the sample, he will come to a surprising conclusion.

Returning to Ardougne

 * 1) Return to Elena in Ardougne and talk to her.
 * 2) She will tell the player to talk with King Lathas. He is located upstairs in Ardougne castle, just south of Elena's house.
 * 3) Talk to the king.
 * 4) Quest complete!

Rewards



 * 3 Quest points
 * 1,250 Thieving-icon.png experience
 * Use of the Combat Training Camp
 * Ability to travel freely through the West Ardougne Gate

Trivia

 * Rings of recoil can be used to kill the level 13 Mourner.
 * Da Vinci is a reference to the famous multi-talented Italian, Leonardo Da Vinci.
 * One thing that lends credence to the fact that the plague is fake is that an adventurer can talk to or fight any citizen of West Ardougne (without a gas mask), while not receiving any damage whatsoever from disease.
 * Ironically the tunnel to West Ardougne can be used to leave the city, but the game states it is closed when trying to go back in.
 * Guidor's wife, even when playing as a female, will still refer to the player as "Father".
 * Even though the vials received from Elena disappear upon teleporting, after talking to the Chemist the player is able to teleport with the vials without them disappearing.
 * Upon completion of the quest, the player's Adventurer's Log reads "With the help of the chemist, some couriers and Guidor, Elena and I found out the plague in West Ardougne was a lie!"
 * When talking with the chemist's assistants, players can say that it is always sunny in Runescape. This is a reference to Runescape having no other weather and the American television sitcom "It's Always Sunny in Philadelphia" on the channel, FX.
 * Before Underground Pass was released, the player was given a Lathas' amulet which had a green centre gem. When the quest was released, the gem turned red.
 * If you tell Elena that it is hard to say good bye after she gives you the samples,she will reply by saying that she has feelings for the player too.
