Walkthrough

Scrying the future

Items needed: 3 empty inventory spaces, 1 gold coin.
Wally slaying Delrith.

Speak to Aris in the tent on the western side of Varrock Square. Pay her one coin and she will scry the future, seeing a vision of the player wielding an impressive sword fighting a demon named Delrith, who terrorized Varrock over a century prior. Delrith was previously defeated by a hero named Wally; just your luck, the demon is being summoned again. Ask Aris where you can find the demon, and she will mention that to defeat him you must first find Wally's sword Silverlight.

Ask Aris, "So, how did Wally kill Delrith?" She will show you the incantation Wally used: write down or screenshot the phrase, as it will be important later on. The word order of this spell is randomised for every player. After telling you the incantation, she tells you to talk to Sir Prysin to help.

Go north to Varrock Palace. Sir Prysin will be wandering the south-west portion of the ground floor of the castle. Talk to him and tell him that Aris sent you. Ask for Silverlight, the weapon needed to kill Delrith. He will tell you that to prevent the weapon from falling into the wrong hands, it was put into a special box that requires three different keys to open it. He has dropped his key in the drain just outside the palace kitchen, and the other two are in the possession of Captain Rovin and the Wizard Traiborn.

Captain Rovin's key

Captain Rovin is located in the north-west corner of the palace on the 2nd floor, up two flights of stairs. Talk to him and tell him that you need the key in order to recover Silverlight to slay a demon that threatens the city. Mention that Sir Prysin said Captain Rovin would give the key to you, to which he will rant about the King being the only one to tell him what to do. Next, ask him why Sir Prysin gave the key to him in the first place, and he'll state the King made Sir Prysin give him the key so that it wouldn't get lost. After this dialogue, he'll then hand over the key, under the condition that you do not allow Sir Prysin to kill the demon.

Wizard Traiborn casts a spell to summon a wardrobe containing his key

Sir Prysin's key

Items needed: Bucket of water.

On the ground floor of the palace, head to the kitchen in the north-east corner of the ground floor. If you do not already have a bucket of water, you can find an empty bucket up the stairs, in the bedroom to the north-east. With the bucket, return to the kitchen and use it on the sink to obtain a bucket of water.

Next, head outside through kitchen door and look for a drain against the wall north of the doorway. Use your bucket of water on the drain. If you do not do this, you cannot obtain the key. The key will be washed down the drain, so you must now retrieve it from the sewer below. Head east, out of the palace, and look for a manhole located south of the palace's east walls. It is marked by the icon on the minimap. Once you find it, open the manhole and climb down to enter the sewer.

The path to Sir Prysin's key in the sewers

While in the sewer, go north-west and follow the path highlighted on the map above until you reach a stream. You should see a muddy patch to your left, next to a pile of skeletons. Examine this and you will find a rusty key.

Wizard Traiborn's key

Items needed: 25 unnoted bones. You can save some time by having all of the bones when you first speak to him. An easy way to get the bones is to kill goblins south of the prison outside of Draynor Village

Wizard Traiborn is located on the 1st floor of the Wizards' Tower, which stands on an island south of Draynor Village. Ask him about the key and at first he won't remember it - but once you ask whether he has 'any keys knocking around', he will recall that he sealed it inside a magical wardrobe, for which he needs 25 regular bones to open.

Once all 25 bones have been delivered, Traiborn will perform his ritual and then give you his key. Note that you can deliver the bones in increments, so Ultimate Ironmen will not need to clear out their inventory to complete this step.

If you die with the key, you will have to pay another 25 bones to re-retrieve it.

The mighty sword Silverlight.

Silverlight

Now that you have all three keys, head back to Sir Prysin in Varrock. Give him the keys, and he will give you Silverlight. Players can drop Silverlight and ask Sir Prysin for another one for free; after the quest he will charge 500. Equip the sword, get any food and armour you may need for combat, and prepare to fight Delrith.

If you have forgotten the magical incantation, you can speak with Aris at her tent in Varrock Square to hear it again.

When you're ready, head south of Varrock, and go east towards the stone circle surrounded by dark wizards. A cutscene will play of Delrith being summoned by the wizards after you enter the circle.

The final part takes place in an instance of the Varrock stone circle, with Delrith and several dark wizards (two level 7 wizards and a level 20 wizard). Level 7 and 20 wizards will be aggressive to players with lower than 15 or 41 combat level respectively. Additionally, upon the cutscene finishing for the first time, one of the level 7 wizards will attack regardless of combat level. The level 20 wizard's maximum hit of 6 can threaten players with a low Hitpoints level, especially if the player has negative Magic Defence bonus. To leave, run to the edge at any time during the fight.

Because the fight takes place in a single-way combat zone, if you are already under attack from a dark wizard, you will need to kill or hide from it before you are able to begin combat with Delrith. It is recommended for lower-level players to approach from the south, and hide from wizards behind the southernmost stone wall until Delrith is nearby. Since the wizards do not respawn in the instance, it is also possible to kill them first, leave and restock, and then return to face Delrith.

Attack Delrith with Silverlight equipped. Despite his combat level of 27, the Silverlight's weakening effect will reduce Delrith's hitpoints to less than that of a cow. When he reaches 0 hitpoints, say the magical incantation. If the wrong incantation is said, Delrith regenerates to full health. If you cannot remember your personal randomized incantation you can return to Aris and she will repeat it when prompted.

Pures and lower levels

For those wishing to attack with magic, wielding Silverlight and manually casting spells will also deal damage. Other methods include flinching him or using Confuse, Curse, or Weaken to make him easier to kill with melee. Ring of recoils can be used for this fight.

If you take too long to finish off Delrith, he will disappear and you will need to leave and re-enter the instance. If Delrith disappears during the dialogue to banish him the quest can still be completed by pressing "continue" until the end.

Congratulations, quest complete!

Trivia

  • While speaking to Captain Rovin to obtain his key, your character will state what happened to Sir Prysin's key even if your character has not yet asked Sir Prysin for it.
  • Waterskins, jugs of water, bowls of water, or vials of water can all also be used to flush out Sir Prysin's key.
