Ruler of the Night!

In the tower outside River Shore City, a frightening aura filled the air.

The aura of the Shadow Diamond was overflowing and even Madeline couldn't approach.

A black star flickered in her eyes. The Book of Nalu seemed restless, as if wary of Marvin's advancement.

She couldn't get any closer because her injury was too severe.

This was also a reason Marvin dared to advance here!

After a short time, the Book of Nalu seemed to have understood the situation and allowed Marvin to advance to Ruler of the Night.

Madeline returned to normal and activated the Wizard Tower's Barrier to stop the aura of his advancement from leaking.

...

In the eternal darkness, Marvin was standing alone.

These logs appeared in his interface:

[Shadow Diamond activated…]

[Absorbing the Shadow Diamond's Domain power…]

[Advancement requirements met…]

[Advance to Ruler of the Night?]

Marvin confidently chose yes!
