This is a plot element within my story. It is called "The Daemon Heart" or simply the Crystal. Its the heart of a god, who consumed everything in a bid to control all things. Though his madness and hunger compelled him to eat himself in the final moment ending his reign. What is left is a heart which though has no mind of its own, carries the same hunger. It was found by an empire who existed thousands of years prior to my story, who pulled it through from somwhere else. The heart gave them all their desires, until the populace ate themselves in a cannabilstic orgy which ended their empire overnight. The object works by giving you what you wish for essentially. But you sacrifice everything else, or more specifically the possibility of anything else. It makes the unlikely likely. By consuming all other possibilities but the one you wish for. So only one future remains. But like terrible gravity. When its exhausted its food source, it collapses what the owner has made upon them, finally eating the user. It also has a habit of making the wish a more extreme version then what the user wishes for. If you want say for example an empire of order and purity. It will compel your followers to "purify" even those who dont want to follow you. The story concerns an empire who kills the protagionists family, who had found the crystal themselves errecting an empire of order. The crystal acts as plot device which pulls the main charecter towards it. When Aren finally gets his revenge and claims the crystal himself. He fails to relise how he himself had been used. It was not Aren who destroyed the empire, as much as it wasnt the empire that killed Arens family. The crystal had mearly exhausted its current meal and wanted a new one. This is how I am explaining it to myself so far. It tells me why a barbarian was able to dismantle a structured empire, why the crystal is as powerful as it is. Though I am wondering if the idea will be to complex for the reader. Or if there is any plotholes which make this object seem to deus ex machina. Any opinions?
