I have a glitch in the Lost to the Ages quest. I get through the "Tonal Lock" portion of the quest. The Wiki states "When you surface from Arkngthamz, three map markers will have been added to your map." I don't have 3 new map markers. I did a couple of restores and replayed, but still no luck. I play on a PC, so I used the console command "setstage" to advance the quest. I tried setting the stage to 135, 150, and finaly just to end it, I set it to 225, the last stage. But no matter what I do, I don't get the quest marked as complete? Any suggestions, or should I just forget about this particular quest?

The other Aetherium shards can be found in Deep Folk Crossing, Raldbthar, and the Dwemer Storeroom outside Mzulft.

What if the Wiki is a lie, and Katria had a Journal with all of the Locations?

What if the Game does not give us arrows to everything in a Quest!

Normally, the quest only give you to one other location, as for the rest two you have to figure it out trough Katria journal.
