Challenge Against God

The protagonist, Astrid Artson, also known as 'THE OMNIPOTENT', is the strongest being in all of the parallel universes. However, he is bored of his god-like powers and the lack of challenges in his life.
Astrid Artson contemplates challenging the real god for a new adventure but is uninterested in the prospect as he believes he is already the most powerful being. Suddenly, a portal-like crack in space appears, and Astrid notices that time has stopped, indicating that someone else can control time. He tries to contact VEL but fails, and then everything goes dark.
Astrid wakes up in a green field and realizes he is facing a new challenge. A Challenge Against God.
