Sir Prysin

Sir Prysin is one of King Roald's knights and is located in the Varrock castle. He is the great grandson of Wally who defeated Delrith 150 years ago, and, as such, is the custodian of Silverlight. To reduce the risk of Silverlight falling into the wrong hands he gave a key to wizard Traiborn, Captain Rovin and kept a key for himself, though he lost it in the Varrock Sewers. You must talk to him to begin collecting the Silverlight keys.

Sir Prysin's name is a play on the word "Surprising".
