Elex 2: System Error – walkthrough

On this page of the Elex 2 guide, you will find the walkthrough for the main mission called System Error. Your task is to take the CRONY U4 drone to the Caalan Altar in the Castle, which is a fairly simple task.

The System Error quest is automatically received after completing the Machines Run Amok quest. Once you have completed this task, you will find out where to locate the Caalan altar and how to reach it with the CRONY U4 drone.

Where to Find the Caalan Altar?

After receiving the task, head over to the CRONY U4 drone. If it is not currently your companion, you can find it in the Bastion. Once there, ask it for help in finding out why the robots have revolted. Together with the drone, head over to the Caalan’s altar which is located in the Castle, in the building where Reinhold (the leader of the Clerics) is staying. The exact location of the altar will be marked on the map.

Once you arrive at the altar, interact with it. You will see a short cut-scene and then a dialogue with CRONY U4 will begin, which will end the quest.
