Grain made it to BlackHeart with no troubles.
He decided to let Violet out on her own, she would need to feed herself and garner more EXP.
He would go and meet with Remus to let him know of the success.
Leon had agreed to teach Grain more about Chaos mana, but only after the war with Astria was handled.
Grain was already powerful enough to turn the tide of the war even further on his own.
He had already learned the fundamentals, just by coming into contact with so much Chaos mana.
As it stood, he could probably learn to wield it properly, in a few decades.
It wouldn't hurt to take his time.
Remus had already agreed to spend the next year before the end of the cease-fire, teaching him about Spatial mana.
Not to mention, he still needed to learn more about Neutral mana. He had only used it by instinct so far, so he would need to actually develop it along with his Spatial mana control.
