Demon Slayer
Starting Point: The gypsy in a tent in the center of Varrock.
Description: Wizards of the dark arts have freed the ancient demon Delrith. Find out how to imprison him again before its too late and he destroys Varrock.
Requirements:None.
Difficulty: Easy, 13+ combat
Items Needed: 25 normal bones, 1 coin.
Reward: Silverlight, 3 QP

Talk to the gypsy at the start of the quest, and give her a coin so that she can tell you the future. She'll tell you a demon named Delrith has been released, and you are the only one who can stop him. She also tells you to talk to Sir Prysin, and tells you how to finish off the demon with an incantation.
Sir Prysin is in the south-west part of the Varrock castle (if you can't find him, then what you can do, is search near that area). Ask him about Silverlight, and he'll tell you that you need 3 keys to unlock the chest with Silverlight, and he'll tell you to talk to Captain Rovin.
Go upstairs and fin Captain Rovin. Talk with him until he gives you his key. Now go back to Sir Prysin.
He will tell you that he dropped his key down the drain (wow...). Go to the northeastern room, go upstairs and grab the bucket, and fill it with the sink downstairs. Go just behind the sink(outside the castle) and you should see a drain. Use your bucket of water with the drain.
Go into the sewers through the manhole that is near you( you will have to go around the castle though.). Once inside, take the left-hand path, and keep looking on your map for a red dot. You should find a key near some bones eventually.
Take the key, and grab your 25 bones from your bank.
Now, go south of Varrock, then go all the way south of Lumbridge(across the bridge, and a bit west of the swamp) and go into the wizards tower. Go up the stairs(or ladder I'm not sure) and find Wizard Traiborn, and give him your bones, and he'll give you the key eventually.
Now, go back to Varrock. Get ready to fight the demon, and go into the stone circle just south of Varrock. You should see the demon. Attack it while you have Silverlight equipped(make sure the wizards don't attack you...), and kill him(When I was level like 15 I killed him in 1 hit.). Choose "Carlem Aber Camerinthum Purchai Gabindo" to vanquish the demon.
Now that you're done, HURRY out of the circle, and away from the dark wizards(if you are a low level like I was) because they're more lethal then Delrith.
