White Raven Island. Labh Salem.
Way past midnight.
It was as if someone had cast a sound-element and gravity-element Skills together, turning the air as rigid and unmoving as a mud lake.
Seven forms of Sin Series Mana were summoned into the surroundings all of a sudden.
Even without Eren wanting to, it turned the space around him into a demonic zone.
This was the same form of demonic corruption on the surroundings that he had encountered when he first came to Labh Salem.
At that time, the Helenbora coven wanted to make use of the special demonic zone to summon the wills of Immortal demons. Instead, they acted sort of like a pathfinder for Eren, allowing him to enter Labh Salem. One could say that it was Helenbora coven that had summoned Eren in this world.
