Cain's instincts were not mistaken. Less than thirty minutes after leaving the battlefield, he stood once again in front of a massive gate, and this one was gray. He focused on the runes and archaic sigils etched into it, trying to understand what the next trial would entail.
Unfortunately, no matter how much he focused or tried, Cain could not sense anything from them. It wasn't that they lacked power, but the power inside the gate was so high-level that even with the Mark of Wisdom, he could not glimpse into it.
The Mark of Wisdom allowed him to perceive the Oniric Truths, yet he could not understand this gate's runes and symbols, which could only mean it was a power on a stage even higher than the Oniric Truths! Such a revelation shocked Cain. After all, the Oniric Truths were the principles of the Crimson World that stood above the Nine Emperyan Suns Universe's Laws and Concepts, so he could not even begin to imagine what could stand above that.
