Engulfed in darkness

"The Darkness will come after you and it has already destroyed almost everything that belonged to the Light", a voice said. This was literally happening before me as some kind of dark vapor or blob engulfed indistinguishable places. An overwhelming feeling of loss.. or sadness.. or something similar arrived. 

It's interesting how different the metaphorical interpretations of the words "darkness" and "light" can be. "Darkness" may refer to something sinister but also to mere obscurity. These two may be intertwined and in this case it would obscurity that leads someone into becoming sinister or even the other way round, i.e. somebody being drawn into having unclear judgement because of the evil things he/she did. This connection between failing to discern things from one another and evil and also on the other hand the connection between intelligence and goodness would be something typical of the ancient Greek philosophy. To me it should be also up-to-date for our times and beyond. Stupidity and the lack of knowledge cause a lot of harm, especially when people don't keep some modesty or see the world as black and white with little to no shades of grey.
