Zeeeeut!
Suddenly, Sychia, Hakros, Kyamakri, Diparxi, and Methysria vanished from sight. But, they were not the only ones.
All throughout the battlefield within a hundred meters, no celestial was anywhere to be found!
This was one of Diparxi's abilities that allowed him to swap the positions of those affected by the ghostly-like beings he controlled with ones placed at a different location.
Diparxi had set this up beforehand in case of an emergency situation where they had to fall back. Needless to say, the presence of two pillars undoubtedly fell under this category.
Unfortunately, this ability was only enough to buy them some time given its limited range and the fact that they were within an area under the influence of a pillar.
When Ourami and Yia saw the celestials disappearance, neither of the two reacted to stop them.
