There is Blade. According to the Bible, Armageddon is the location where the final battle between God's Army and Satan/Lucifer's army will take place, as part of the End of the World scenario.

To be quite honest Mikachu, I wouldn't dwell on such things too much. I'm not sure on this, but are you a Christian? And by Christian, I don't mean the religious nut-jobs and douchebags that believe that they're the reincarnation of Jesus and believe that gives them the right to persecute others of different lifestyles/beliefs/choices etc. I mean a Christian who whole-heartedly tries to do good, loves others unconditionally and tries not to wrong others by actions, thoughts, being judgemental, etc.

In the Bible, the apostle John had some revelations that were shown to him by God about the impending end of the world with similar images such as the ones that came to you in your dreams. Maybe it really is a vision from God about the future. I believe so. Now I'm hardly a devout Christian by any means (Lord knows I don't pray enough and be an overall good person to others to justify it), but I would just take it with a grain of salt. If you feel the need, just pray about it or write it down in your journal to maybe think it through a bit more thoroughly.

Hope I was able to help you a bit
