Gavros Plinius, a member of The Synod, retrieved the artifact and brought it to Mzulft with his fellow members of the Synod. However, he was killed by the Falmer that inhabit the Dwemer ruin in the process. The Dragonborn finds the object on a Falmer mage. Once found, make sure to have a conversation with Paratus Decimius and not a fight. If you have started fighting him, exit the area through a door and come back. He should then be peaceful. Place the crystal where the lenses are, use Flames and Frostbite on the crystal to move the lenses and use the three buttons so that the light hits every lens.
This section contains bugs related to Focusing Crystal. Before adding a bug to this list, consider the following:
- There is a glitch that sometimes won't allow the user to change the size of the crystal, thereby making the mission impossible to finish.
- The Crystal will not always spawn. Again, making it impossible to finish, unless the console command is used to get the item.
- It may occur that the Falmer carrying the crystal will float in the air after death, making it impossible to loot his body. This can be resolved by exiting and re-entering the area.
