@Crustiel Thanks for coming back to me. So for my character I had her whole story planned out, and I've got to say it's pretty dark ... and i planned the whole story including the dark matter but then the blood idea comes, which like you said has a darker tone which i feel blends a bit better into my characters past and stuff. But like you said , im gonna have to go over her external and internal factors and which ever one i feels suits ill choose... and ill let you know..
Thanks love for replying. It really helped. :)
