Go down the manhole which Is to the south-east of the drain. Go down the North-Western path and you will find the key.

Go back to the castle, go to the north-west room and climb the stairs twice. Talk to captain Rovin and ask him for his key.
Key 3:
Having the 25 bones in you inventory, go to Draynor Village and go south to the Wizard Tower. Climb up to the 2nd floor and talk to the Wizard Trailborn. He needs the bones which you have, give it to him to get the key.
Silverlight Part 2:
Head back to the Castle and give Sir Prysin the keys. Once you have the Sword Silverlight, go to the bank or make sure you have food and armour and if you wish your best weapon.
Killing time:

Talk to the Gypsy and she will tell you the Magical Incantation, write this down, as the words are random.
Go south to the Stone Circle, and wielding Silverlight defeat Delrith. Just before he dies you have to say the Incantation.
Congratz you have completed Demon Slayer.
Reward:
3 Quest Points
Silverlight

The sword Silverlight is equal to a Steel Longsword, except and added +1 Magic Defence bonus. When used to fight Lesser, Greater, Black or Abyssal Demons, Silverlight increases damage by 60%. Doing 11 damage to a non-demon, will be 17 to a demon. But rune weapons or any better stat weapons to Silverlight should still be used instead as Silverlight has low accuracy.
