It haunts us, it calls out our names. To humans, the unknown is a dangerous, uncharted land. Humans fear what they can't understand.
Strange occurences have happened in and through out history. Humans think of them as ledgend, myths made up to frighten little kids. However, there are those who are wise enough to know the truth when they see it. That somethings are not what they seem. They know that creatus exist that drink the blood of humans and animals. That there are people tormented by curses day in and day out. That there is a whole other world that exists beyond the scope of human lives and thoughts. Some creatures mean us no harm. Others call for our destrution out of amusement, spite, or hatred.
