As he grows stronger, he uncovers a prophecy that foretells the rise of a Prime Warden, a hero who will either save the Nexus or doom it to eternal chaos.

In the beginning, I just wanted to solve life problems.

Then, I didn’t want to admit defeat, I didn’t want to just leave in such a daze.

Finally, as I have always insisted, when you decide to invest in something, you must do it to the best of your ability!
