The Duke
Start the quest by Speaking to Duke Horacio whom is located in the Lumbridge Castle. His room is the north room on the middle floor. Ask him if he has any quests for you. He will respond that he doesn't really have a quest but he did just recently discover a strange talisman. He asks if you would take it to the Head Wizard in the Wizards' Tower. Once you accept head your way to the Wizards' Tower.
Follow the path west out of Lumbridge which goes towards Draynor Village. Once you hit Draynor go due south until you reach a bridge. Cross the bridge, enter the tower, and climb down the ladder located in the west room.
The Wizards
Speak to Wizard Sedridor and tell him you are looking for the Head Wizard. He asks for the reason, and after you tell him hand the talisman over to him, for he is the Head Wizard. He is amazed at the talisman and says he thinks it's the last piece to the puzzle! He needs some time to study the talisman; he will ask you to run an errand for him. The errand is to take a research package to a man in Varrock who runs a Rune Shop. Accept and he will give you the research package.
He gives you directions to Varrock:
"Head Directly North from here, through Draynor Village, until you reach the Barbarian Village. Then head East from there until you reach Varrock. Once in Varrock, take this package to the owner of the Rune Shop. His name is Aubury."
Once in Varrock follow this map:
Now speak to Aubury to give him the package.
He asks for a few moments so he can look over the package. Speak to him again and he will hand over some notes to take back to the Head Wizard. He will offer to teleport you back to Wizard Sedridor. Return to Wizard Sedridor and speak to him. He will let you in on the secret of runecrafting and then you will hand over the notes...
