Step 1
Talk to Doric.

Head over to Doric in his little house north of Falador. He will tell you that his business is dying because he isn't receiving orders anymore. Doric also mentions that his son hasn't returned home after graduating from his studies in Keldagrim. Doric's last remaining customer is Sir Amik Varze of the Falador White Knights. In order to keep his final customer, Doric wants to make him some high quality samples to keep his business. Doric asks you to get him some high-quality copper and tin ores.

Step 2: Obtaining ores
Go to Dwarven mine
Go to Varrock mines
Go to Rimmington mine

Doric gives you an Ore bag and Mining sites map to help you in getting high-quality ores. The map shows that you must obtain ore from 4 different mines.

1. Dwarven Mines
2. Southwest Varrock Mine
3. Southeast Varrock Mine
4. Rimmington Mine

Walk over to the Dwarven mine which is east of Doric's house. Once inside, head to some copper rocks and mine it. After successfully mining Copper ore, a Living rock brawler will attack you. Kill the Living rock brawler and it will drop High-quality copper ore. Pick up the High-quality copper ore and it will go directly into the ore bag.
Note: You may drop the Copper ore as it is not needed.

Now teleport to the Varrock lodestone. Head west to reach the Southwest Varrock Mine. While at this mine, mine Tin ore. Just like at the dwarven mine, a Living rock brawler will attack you. Kill it to receive High-quality tin ore. You also receive a broken anvil amulet. Walk east to reach the Southeast Varrock Mine. Mine Tin ore here, and as per usual, kill the Living rock brawler and receive another High-quality tin ore. You also receive a wizard's diary.
Note: You may drop the tin ore as it is not needed.

Now teleport to Port Sarim and head west to the Rimmington Mine. Once arriving at the mine, a cutscene will appear. This cutscene will show a Concealed Dwarf and Dark Wizard Elijah talking to each other about some ore. They are discussing their plans but they hear a noise and teleport away so they don't get caught. After the cutscene ends, head into the mine and mine some Copper ore. Once again a Living rock brawler will appear. Kill it to receive another High-quality copper ore. You now have all the needed ores, so you may teleport back to the Falador lodestone to head back to Doric.

Step 3: Making equipment
Talk to Doric
Create weapons
Head to Artisan's Workshop

Talk to Doric and you will explain that you got attacked by Living rock brawlers and you overheard the Wizard and Dwarf. You will bring up the Broken anvil amulet and Wizard's diary that you found while getting the ores. Doric will explain that the Broken anvil amulet looks like the Gofannon amulet and the diary explains the plan against Doric. Doric will now ask you to use the high-quality ore to make weapons for his client. Withdraw the ore from the ore bag and use the high-quality ore with Doric's furnace to create High-quality bronze bars. Proceed to Doric's anvil to create a High-quality bronze sword and High-quality bronze dagger. Now that the weapons are made, Doric will inform you that the weapons need to be finished by Aksel at the Artisan's Workshop. The Artisan's Workshop is located in the south-east corner of Falador.

Head down to Falador to speak with Aksel. Aksel will agree to finish the weapons if you talk to Sten to finish out the status of the tracks in the basement. Head down the tunnel to speak to Sten. Talk to Sten to get the figures. Sten will let you help build tracks, but you decline. Head up the tunnel and speak to Aksel again. You tell Aksel that the progress is slow and Aksel hands you the Finished bronze sword and Finished bronze dagger. Now that you have the finished weapons you can give them to Sir Amik Varze. Head north-west to the Falador castle to speak to Squire Cerlyn.

Talk with Squire Cerlyn and explain that you have weapon samples for Sir Amik Varze. The Squire informs you that someone else is in a meeting with Sir Amik Varze and they are showing him weapons. You explain that you were sent by Doric and the other person is an impostor. A cutscene starts with Squire Cerlyn taking the weapons and informing Sir Amik Varze that the Concealed Dwarf that he was meeting with is an impostor. The Concealed Dwarf reveals himself to be Boric, who is Doric's son. The cutscene ends with Sir Amik Varze kicking Boric and you out. You end up back at Doric's house with Boric.

Step 4: Finishing Quest
Talk with Doric
Settle Fight

You are now at Doric's house with Boric but they are in the middle of a family feud. You must calm both of them down. You must choose topics for discussion that are least likely to start another fight between Doric and Boric. You can do this by having Doric explain that he was only trying to do what was best for his son and by Boric explaining to Doric why he didn't want to be sent to Keldagrim.
Note: If you don't settle the dispute fast, you may be forced to start over again.

After the dispute is resolved, Doric and Boric agree to continue their family business together. Doric asks if you want to help them with their business. All you have to do is two tasks and you will be a part of the business. First you must clear the rocks on the track underneath the house by mining them. Secondly with the High-quality bronze bars you were given, Doric wants armor and signs for the front of his house. Head over to Doric's anvil to make an Ornamental platebody, Ornamental chainbody and Shop sign. Hand them over to Doric and a cutscene will occur. The cutscene will show Doric opening his business with a party. Congratulations, Quest complete!
