I don't know if anyone has thought about this, but one thing is she died by the eye of onyx. You may say, someone else was there instead of Blister. That's not possible because everyone knows her to much to mistake her for someone else. You may say, Blister was an animus dragon and cloned herself or someone else cloned her. That's not possible because if she or someone she knew was an animus dragon, she would of not went to war. Instead she would of just killed her sisters and mother. If anything is wrong with this, please tell me! If you disagree, please tell me your idea! If you agree with me, Ty!
