Chapter 519: True Nightmare

'What is a nightmare?'

Ever since obtaining Cassian's abilities, this was a constant question that remained on Leo's mind. Just what did Shadow Nightmare represent?

At first, he had more than one plausible theory, but as he used the ability further, Leo realized that none of his theories could be proven in their entirety.

At times, the Shadow Nightmares broke through the limitations that he envisioned, and at other times, they failed to live up to his specific expectations.

Even then, Leo didn't give up. He was still hoping to get a firm grasp on all of Cassian's abilities before he left this world!

However, after opening a few more doors to use Shadow Nightmare in this Gate, Leo couldn't help feeling that his old way of thinking was quite shallow.

'Does it really have to follow a certain setting?'
