This was something to explore once he got even stronger. The dark magic practitioner he had encountered could have been very dangerous if he was properly trained. Who knew what powers and horrors existed there? Though all of this was in vain, as currently, he had no idea how to even enter said dimension.

Now, no matter how he stretched his senses, he found nothing out of the ordinary other than a quickly fading echo of foulness.
