Where to find Stone in the Old Camp
Stone is at the Old Camp, in the inner ring. He is a blacksmith and works on the armors for the guards.
You can meet him only after passing the entrance guarded by Thorus, so you'll have to join a guild or bring 1,000 ore pieces to Thorus to buy him out.
Pass the gate, turn left and you will find a wooden roof on the left, where you will see Stone working on the forge.
