Look. I haven't been around long on this site. But I Require some help. A Few years ago while i was first immersing myself into the world of magic and witchcraft. I found myself in a strange situation. I have 2 hearts. The One normal and a second made of a sort of energy. For years I have asked people around me. Those attuned can feel the beat as it pushes my energy like blood. I can feel it is simply more than a normal Chakra, It behaves differently. Reacting to my mood and my spells, matching the frequency of the surrounding energy. I want to know what if anyone knows anything or have any ideas.
This could be your second origin which is a second heart but made entirely out of pure energy.I yet experienced a friends but not of my own. That heart heart holds special energy that is used when you need it the most. It will keep its energy and never fade but take of it so it won't die. If it does die it won't effect you, but you will feel a little weaker cause that energy has left. Its not like you can't walk or anything, but you will feel an emptiness.
