Silverlight keys

First Key
Items Needed: Bucket of water

The First Silverlight key is in the blocked drain, out near the caged bear and the yew trees. Use your Bucket of Water on the drain. This will flush the key, stuck in the drain, down into the sewer. The sewer is found down a manhole, across the road from the museum. Go down the manhole and take the short path up to the zombies. The zombies can't hurt you, because there is a river seperating them from you. The key is found in the corner of the broken walls, in a pile of mud. It is marked "Rusty Key"

Second Key
The second key is the easiest of the keys. It is found upstairs of the castle. Go to the tower North West of the castle and climb up 2 flights of stairs. talk to "Captain Rovin" After a while of talking to him, he will give you the Second Key.

Third Key
Items Needed: 25 Bones The third key can be found in the Wizards Tower found South West of Lumbridge, and South of Draynor Village. Go up 1 set of stairs and talk to Traiborn. Give him your 25 bones He will then give you the third key.

Note: If you forgot your bones, theres a chicken under the tower, it re-appears regularly and is an easy way to get bones. there is also a "wizard level-9" near the chicken. I killed the wizard 3 times and got 6 laws of it...pretty sweet eh?
