They say that death is as inevitable as dusk. Just like a day is followed by a night, is life followed by death. What connects these both events is that their nature is cyclical. Eventually darkness fades and light takes over, if only for a while. The followers of the dark know that there are many aspects to death. It can be swift, or it can be slow. Sometimes it's gruesome while sometimes more merciful. While being subjected to gangrenous coils is not at all a painless way to go, the death may be relatively swift in the hands of an experienced spellcaster.
