Lisa continued deeper into the tower. The interior was enormous, with dark corridors extending in every direction and countless rooms and training chambers hidden throughout the structure. However, she had no interest in exploring them yet.
She already knew where she needed to go.
After traveling through several corridors, Lisa eventually arrived at the central chamber.

Lisa smiled.

The formation immediately responded.
The entire tower began to tremble as an enormous amount of Dark Energy gathered within the chamber.
It didn't take long before the air became colder, and the shadows surrounding Lisa began twisting violently.
A moment later, the first figure emerged from the darkness.
