I felt my Aura expand little by little, with Nix's help it was getting easier for the first few kilometers, but over time the distance was increasing and becoming a burden on my mind.
Also, the miasma I was huddled with was starting to lose control and trying to eat away at my conscience, I had to keep my will firm to bear it.
It took 5 hours for my Aura to travel all over this place stopping only where there was no more miasma, I also managed to keep the rhythm of harmonization, my pure dark element mana harmonizes perfectly with the miasma.
Nix was a big help for this, but in the end, I needed Layla and Sakura to help me, each of the three represented an energy aspect like mana, spirit energy, and Ki.
They made it easier to withstand the pressure on my mind and maintain attunement even as my will was corroded by malice in the miasma all this time.
