The Golem Registry is a side quest encountered in the Anvil of the Void.
The easiest way to acquire this quest is to wait until you're in the Anvil of the Void chamber, after the final boss fight has been completed. There is a large statue of a stone golem holding a tablet to the right of the exit as you're leaving the chamber. It lists the names of many dwarves who were turned into golems. Examine it, take a copy of the names, and return it to the Shaper Czibor who is located in the Orzammar Shaperate.
- If you inform Shaper Czibor that you're heading to the Deep Roads he will ask the Warden to keep an eye out for ancient treasures or manuscripts as the Shaperate is interested in them and will pay a good price to get them back. This is a reference to this quest.
- There is, however, an unofficial workaround via a third party mod.
