After finding traces of a different kind of mana, Grain contacted Remus.
He expected it to take a few hours or maybe a day to get his attention, yet it took merely a look at the sky.
"Everything okay?" Remus asked from beyond a tear.
Grain simply shook his head and Remus stepped through.
After Grain explained everything Remus began to speak again, reiterating what he already knew.
He had seen it back in Astria, the powerful grey mana used by the most powerful person on the human continent.
Void mana was the specialty of the King of Crane, Grains other grandfather. He was the only known user and both Remus and Leon, have yet to figure out how to even sense it.
Remus was astonished when Grain showed him the grey mana, making him ask at least two dozen more questions.
It was a long drawn out conversation, but Grain was able to at least organize the knowledge they had.
