Oldak is the greatest inventor of the Dorgeshuun, an advanced tribe of cave goblins. He spends most of his time in his house in north-western Dorgesh-Kaan.
Oldak is known for his excellent magical skills, a trait uncommon amongst the cave goblins. He seems to view magic somewhat like a scientist; his home is filled with lab coats and strange metal instruments, such as the Oojimaflip, Thingymajig and magic balls. Only after Dorgesh-Kaan's opening was he able to do much; the lack of available runes in the hidden city made things difficult.
Oldak will make players Dorgesh-kaan spheres, if provided with molten glass, either noted or un-noted, and two law runes. He will coat the molten glass in the crushed law runes, and once the glass hardens, the orb will have magical properties. When broken, the orbs will teleport players to one of several random areas in Dorgesh-Kaan.
During Another Slice of H.A.M., he will also make players goblin village spheres. After the quest is complete, he will make players these spheres in the same way as Dorgesh-Kaan spheres.
If a player inquires about the magic he has discovered, the cave goblin will explain some of his more recent discoveries, which will boost or drain the player's Magic or Runecraftskill by up to two levels.
Talk to Oldak and ask "What have you discovered?", and you will get a different response depending on what skill is affected and whether it was drained or boosted. This can be repeated for the desired boost.
Thieving chest
On the top floor of his house is a chest which can be opened with a lockpick if a player has a Thieving level of 52. The chest can be opened once every 3–5 minutes, and the loot obtainable from it is different from the loot of the other chests around the city.
