There are just a few specific pieces of information that I'm missing.
Once those blanks are filled, we'll be ready to activate the final obelisk. Then, it'll be a race to discover the Coffer of Promise before Schnottz and his cronies can.
Those fools are excavating this site as fast as they can. They're ruining more than they're looting!
Go to the obelisk and rummage through their booty, <name>.
See if you can find our missing pieces.
Progress
Were you able to find anything interesting, <name>?
While working on Reduced Productivity at the same time, once both quests are finished, a cutscene will be triggered showing one of the Schnottz workers discovering the body of one of his comrades. He raises the camp alarm, and players see Myzerian take on his black dragon form.
