The Kejars

Northern spent quite a while in his soul scape; even after he was done mapping out, he wanted to get a total number of souls that resided there.

Which shockingly were a lot. Northern, since he gained the soul world ability of the Void, had killed over ten thousand monsters!

It was really shocking to him.

And these were monsters that had died by his sword alone. The ones that died by the hands of his Void summons were not included. They consumed the soul of whatever they killed and rendered its core to him as talent fragments.

So, the monsters in the Limitless Void could only be put there by him alone.

Which made the realization that he had killed by his own hands over ten thousand monsters appalling.

The souls that were ushered in by Soul Taker's demise were not accounted for in that ten thousand. And the total souls that were liberated were about a thousand, with a hundred of them being Tomb Kings.
