Summary:

Just the story of a necromancer and his eventual army.

Currently, the only major thing of note is a pretty fleshed out magic system. No set list of spells or specific incantations. Just rules similar to the laws of physics, within those laws you can do whatever is possible.

Updates:

I work Sunday thru Wednesday and updates tend to revolve around my scheduled days off. Currently, I release content as I feel it's ready for release because that's what I myself would prefer from an author.

Warnings:

This story is graphic.

blood/necromancy magic that requires self-harm to use. 

explicit descriptions of sexuality. (though fairly tame outside of the marked chapters, at least compared to said chapters)

and is generally darker in tone.

If you're concerned you might start to read only to be turned off by these elements.

See

7. Teetering on the Edge for an example of the graphic nature of violence or

9. Explicit Content for a fairly self-contained example of the most explicit of the sexual content.
