Tainted by Darkness

Short story collection.

They gather in the dark: those who did not traverse to face their judgement when their mortal shells expired. It is within these darkest regions that the veil to the mortal realm is weakest.

Sentinels stand at each of the seven gates, commanded by the gods to guard against the spirits that try to break out of Akasha.

But there are some who manage.

Many come seeking closure, demanding retribution for wrongs done onto them by their mortal brethren. No longer visible, they collate shadows, merging with the darkness to assume corporeal form that allows them to move among you, yet remain hidden; at least until it's too late to do anything more than beg for mercy.

For darkness taints even the purest of souls.
