Bab 329: Bladed Ghostmancer, A Titled Ranker's Strength

Since Altair had employed his Lightless Shroud to deal with the weaker opponents on the field that crossed a certain threshold, not many of them could make it past the small perimeter he set.

Due to the effects of the Lightless Shroud, if a player approached Altair, they'd walk into an unknown situation with their sense of sight disabled. 

If not for his Eye of Darkness reaching the Shadow Illumination level, Altair would have also faced the same repercussions of having his Lightless Shroud active.

In fact, this was the reason why Zephyr had him train the ability before moving on to accepting the power from the Throne of Deathless Night. 

Had he simply sat on the throne without awakening the Eye of Darkness, what he would have received would not allow him to utilize the Lightless Shroud at maximum capacity.
