The Knight's Sword

Starting Point: Courtyard of the white knight's castle

1. Firstly, talk to the squire about his emergency, and he’ll direct you to Reldo, who is located at the Varrock Library, which is on the ground floor at the back of the castle. Reldo will give you the location of the last remaining Incamdo Dwarf in all of Runescape.
2. Head southwest of Port Sarim, to the cliff where Thurgo lives.
   
   
   

   He will bluntly refuse to talk until you give him a redberry pie. He needs a picture, so head back to the Castle in Falador. Talk to the Squire to find out about the picture. Proceed to go up to the south side of the third floor. Search the cupboard in his bedroom WHILE SIR VYVIN IS NOT IN THE ROOM.

3. Go back to Thurgo, with the picture, iron bars, pickaxe, armor, etc. if wanted. Talk to Thurgo and he will mention that he needs Blurite ore. Enter the cave to the east, which is on the hill next to his house. Head into the cave until you enter an ice room. Run past the Ice Warriors and Giants to the back wall, mine some Blurite ore and QUICKLY get out of there.
4. Take the two iron bars and blurite ore to Thurgo and he’ll make the sword. Take it back to the Squire for your reward.
