Shadow of the Storm

Agrith Naar
Speak to Father Reen, who is just south of the Al Kharid bank. He gives you a silverlight and tells you about a group of dark wizards, led by a man named Denath, are attempting to summon an evil demon, Agrith Naar (You can use the drop trick to obtain any number of silverlights). When you offer your services to stop the summoning, Reen tells you that he already has another plan. He wants you to help the wizards with the summoning and then kill the demon once and for all. He directs you to see Father Badden in Uzer, for further information. Travel to Uzer, which is east of the Dominion Tower.

You can take a magic carpet there for 200 coins (or 100 coins with the ring of charos and whether you've played the Rogue Trader activity before). An enchanted broomstick from Swept Away is especially convenient for reaching Shantay Pass, and for doing the quest itself, due to its ability to bring the player near both a musician and a bank, but also near the area of the quest.

Blending Into the Dark
In Uzer, talk to Father Badden. He will ask you to infiltrate the dark wizards who have made base inside the Ruins. Enter the basement below the temple ruins, and try to enter the portal to the Thammaron's Throne Room in the north part of the basement.

Evil Dave won't let you in if you aren't wearing at least three pieces of black clothing, because "you aren't evil enough".

Some of the ways of appearing 'evil' to Evil Dave are: The following will not work:
 * Dye a desert shirt and a desert robe black by picking a black mushroom outside of the dungeon and grinding it into black mushroom ink.
 * Black cape (obtainable from a Highwayman for example) or a black Fremennik cloak.
 * Wear Black dragonhide armour. (Spiky vambraces will not work but black d'hide vambraces will)
 * Obtain the black wizard robes and hat dropped by Dark wizard
 * Wear any three Black armour items
 * Buy a Priest gown top and bottom from the Fancy Clothes Store in Varrock
 * Shade robes
 * Culinaromancer's gloves 5
 * Dark mystic robes
 * Ghostly robes


 * Eye Patch
 * Highwayman mask
 * Void knight robe/top
 * Elite black armour
 * Vyrewatch clothing
 * Mime boots
 * Black naval shirt/slacks
 * Black defender
 * The Grim reaper hood
 * Dagon'hai robes set
 * Rogue equipment


 * Gloves of silence
 * Black Cavalier
 * Clan Cloaks
 * A Blood'n'Tar Snelm
 * Black boots
 * Black claws
 * Black armour (t)
 * Black Mask
 * Classic cape/hood
 * Obsidian Cape
 * Black Flowers


 * Klank's gauntlets
 * Toktz-ket-xil
 * Black Afro
 * Royal Cape
 * Lunar cape
 * Zamorak cape
 * Ardougne Cape
 * Warlock cloak
 * Desert outfit
 * Desert boots
 * Regen bracelet

You also need to dye your Silverlight black using black mushroom ink. If you do not, Evil Dave won't let you enter the demon's lair. You no longer have to do it when you start the quest. You can now dye it before you start the quest. You do not need to wield the dyed Silverlight in order to enter; you can wield another weapon, as long as you have the dyed Silverlight in your inventory.

Talk to Evil Dave again, and ask to join the cult. A cutscene will start, showing Evil Dave leading you to the leader of the group, Denath.

Denath will accept you into his group because another member, Josef, has disappeared. Denath will tell you that he needs your help to summon Agrith Naar. He will also tell you the incantation to use, which is different for everyone, so you need to write it down.

Josef
Talk to Jennifer, one of the dark wizards, to get a demonic sigil mould. Go to Al Kharid (either by magic carpet to Shantay Pass or by teleport), and use a silver bar on the furnace to make a demonic sigil.

If you haven't done so, stock up on potions and food for your final battle with level 100 Agrith Naar. You no longer need your black outfit to enter the portal. The demon uses magic and melee attacks, so one good strategy is to load up on melee-protection armour. For example, dragon armour) and Protect from Magic/Deflect Magic together. If you already are wearing black dragonhide armour for your three pieces of black clothing, you can also range the demon. The dragonhide will protect you from taking too much damage from the demon's magic spells. Prayer potions may be necessary. Be sure to use Silverlight to strike the final blow.

Return to Uzer, enter the demon's lair again, and talk to Matthew. He will tell you about Josef and a book he had found.

Go back outside, and talk to the Clay golem. It will tell you that Denath killed Josef, but not before Josef hid a large book in one of the broken kilns.

Look in the kilns around Uzer (do not forget to check the one north of the magic carpet) to find a Demonic tome. You will also now find Father Reen standing outside the temple's ruins. If you want, you can have an interesting discussion with him about his religion.

Read the book, then return through the portal and discuss the content with Matthew. Matthew notes the incantation for summoning the demon that's written in the book is backward to the one that Denath told you to say.

Calm Before the Storm
Denath will now call you over to take your place and lead the incantation. (Make sure you have your Silverlight with you) Using your sigil, chant it in the order that Denath told you. It is different for each person. (You can ask Denath for the incantation in case you forgot.)

After finishing the incantation, Denath walks to the centre of the magic circle that appears and goes into another dimension. Denath was Agrith Naar all along, and you actually desummoned him by saying the incantation backward. This particular demon is much more powerful in his own dimension, so you need to resummon Denath to defeat it.

Do not forget to pick up the sigil that Denath dropped or you will have to make another one. Evil Dave, Eric, and Tanya will run away. Chase after them through the portal. The examine text on the portal now reads, "It looks like the magic is failing".



Note: When you exit the portal, you will occasionally take small amounts of damage from falling rocks in the basement and in the sandstorm outside in Uzer.

Tanya will be killed by the ghosts in the basement, so pick up her sigil. Talk to Evil Dave, who will tell you that Eric was killed by a collapsed ceiling and will give you Eric's sigil. Tell Evil Dave to return to the lair. He will go back. Go up the stairs and talk to Father Badden and Father Reen, and give them each a sigil. They will to go to the demon's lair.

Talk to the Clay golem upstairs. He will tell you he was programmed to never help summon demons. Go back into the basement, take the strange implement from the north-west corner, use it on the golem, and take out the scroll about demons. Talk to the golem again, and it will agree to help you now. It takes the third sigil.

If you forget to pick up a demonic sigil, you can make another one with a silver bar and the demonic sigil mould.

Go back into the demon's lair, and talk to Matthew to get everyone to stand in the circle.

The Darklight
Take your place in the circle, and use your sigil to chant the incantation in the order you read in Josef's book(it is the same incantation you used before just backwards). Agrith Naar will appear in the circle, very angry that you summoned him. He will kill Matthew, and then move to attack you.

By default, he uses melee up close and casts Fire Blast at a distance. If you use the Protect from Melee or Protect from Magic prayer, he will automatically use the alternate attack style. Agrith Naar hits up to 110 life points with melee and 100 with magic. An extremely easy strategy is to buy or loan a pair of dragon claws. It you are on the weak side of this fight (under 90), then two of the claws' special attacks plus silverlight should do the job.



You must hit the final blow with Silverlight. However, if Agrith Naar dies from poison, and as long as you have Silverlight equipped, it will still be counted as a kill. A dwarf multicannon cannot be used to attack Agrith Naar. If you try to set one up during the battle, you get the message "Some kind of demonic magic prevents the cannon from functioning". If you are over level 90 in combat and have level 37 prayer you should have no problems defeating him, especially with the dragon dagger and you shouldn't need any food or potions whatsoever.

When the demon is dead, unequip your Silverlight. A message will then appear telling you that it has merged with the demon's blood, and will turn into Darklight.

You will then be able to choose the skill you wish to receive experience in. If you accidentally do something to make the message disappear before choosing (for example, turning off a prayer or walking away), un-equip then re-equip Darklight and it will appear again.

Congratulations, quest complete!

Cultural References

 * Tanya says "All will love me and despair." This line is similar to one spoken by the elf Galadriel in The Lord of the Rings, though her words were "All shall love me and despair".
 * During the quest, if you talk to the clay golem and ask why Badden hates him, he will say, "He should know that I could never hurt him. The first command in a golem's mind is that it cannot allow a human being to come to harm." This is probably referring to the Three Laws of Robotics from Isaac Asimov's book I, Robot. The first of the three laws states: "A robot may not injure a human being or, through inaction, allow a human being to come to harm."
 * Eric, one of the dark wizards, might be a reference to the novel Eric, in which the protagonist, also named Eric, tries to summon a powerful demon for riches and a beautiful woman.

Trivia

 * Upon the completion of this quest, one's Adventurer's Log will read: "I joined a demon-summoning group in order to kill the demon when it was summoned. It turned out the group leader was the demon!"
 * Before he dies, Matthew speculates that Ellemar must have trapped Agrith-Naar in human form to stop him from using his magics. "That must be what the last pages of of the book said," Matthew guesses. "So the reason he assembled us was to send him back to his own plane, where he would be much more powerful! That's why the ritual was backwards!"
 * When you first meet Denath, he will say Agrith-Naar could conjure an abyssal whip or dragon chainbody for the player, but says it wouldn't be necessary as Agrith-Naar would give them control over life and death.
 * When Patrick says he will get a small piece of coloured paper, he is referring to a partyhat, one of the rarest and most expensive items in the game.
 * If you removed the gems from the throne during The Golem, Evil Dave will complain that the lack of gems diminishes the evil ambiance of the throne room.
 * When Tanya is killed by the ghosts, her life points bar is full, even after she takes damage and dies.
 * If you talk to Eric and walk away before he's finished talking, he will do the "Angry" emote and say "Don't ignore me!"
 * If you speak with the rug merchant while the sandstorm is brewing outside the temple, he will refuse to help you, exclaiming "Anyway, I'm not leaving the rugs alone in this weather. They could blow away!"
 * After completing the quest, if you talk to Juna, your character will say, "...So Denath was Agrith-Naar all along! But I managed to summon the demon again and slay him." to which she replies, "Agrith-Naar was one of the demons my master banished at the end of the great war. It seems he found a way to work around the ban on direct intervention."
