In a moment you will face a difficult choice. You will have to decide if you want to kill Abraxis and The Lord of Hollows or maybe save them? Every decision has consequences.
To get to Abraxis, you have to deviate slightly from the main path. Kill the opponent shown in the picture above. You can use Salvation for this purpose and attack your opponent from a safe distance.
Activate the Storm Hollow and jump into the air whirl.
Opposite, you have one illusionist to defeat. The corridor on the left leads to a demon fight for which you will receive an additional Artifact.
Stand in the middle of the elevator to enter the throne room of Abraxis.
After a short cut-scene you will have to make an important decision - whether you want to kill Abraxis, whether you agree to his conditions and kill The Lord of Hollows. You don't have to worry about fighting because Abraxis is a surprisingly easy opponent. Simply avoid his attacks and perform counters.
For killing Abraxis you will receive his soul, which you have agreed to deliver to the Lord of Hollows. If you decide to save the demon, you will see a short cut-scene with him. This will not give you any additional items.
After gaining Abraxis' soul, you can go to the Lord of Hollows. Here you will face another important choice. If you decide to spare the Lord of Hollows, you will receive a key item - a mysterious stone seal. Killing the Lord of Hollows will not reward you in any additional way.
The mysterious stone seal is an object that will influence the final scene in Darksiders 3.
