The Bloody Tales of Sebastian's Lineage

There is a different world out there that looks just like ours. In that world people are driven by revenge as their primary motivation. Some people have gone mad with their obsessions and some people naturally derogated their mind believing in tales and rumors that are hard to believe for a normal mind. At the end it is all about survival. Some People left with no choice but either to kill or die. And there are other who have a choice to free from the chains of these violence- But they chose to stay.
