After this experience, Sylas was finally starting to feel that something was off. The difference between the Skills with and without his Rune Soul was too drastic.
According to his understanding of the Rune Realm he thought he was in—Rune Breath—he shouldn't be able to do all of this. He had thought that maybe he was underestimating Rune Breath a bit too much, but the evidence was piling on further and further.
So he chose to ask the Madness Key about the various Rune Realms.
Rune Sight. Rune Visualization. Rune Enlightenment. Rune Breath. Rune Flesh. Rune Soul…
Rune Essence. Rune Vitality. Rune Spark.
These were the nine levels of Rune Mastery. Though, there was something odd about the Madness Key's response that made Sylas feel as though there might be more to this than what met the eye.
Still, after reading their descriptions, Sylas was almost certain he had somehow leapt over Rune Flesh and entered Rune Soul directly.
