Dolem is a dwarf who needs some money and knows a new way to get it. When you start the quest The Thanos Vaults, Dolem promises you some emeralds after you bring him some gold from the Vaults.
Enter the underground city of Thanos. Walk down the stairway from the entrance and continue on the wide way. You will reach a four-way intersection of paths. On the right path in front of you will be a sign showing the direction to the treasure room. Follow the right path and you will find Dolem at the end.
