Entropy

If the idea of the Eldar or Chronos was difficult to understand or talk about, Entropy is potentially even stranger. When everything was created so was Entropy, it is the devourer of all things and the ultimate destruction. Within the fluid concept of time entropy will finally have devoured everything, including the Eldar. Finally Entropy will devour Chronos and then because Entropy cannot exist without time it will devour itself. In the very instant (a vague term considering that time no longer exists) that Entropy fully devours itself it will give birth to Creation. In the instant (again funky because time doesn't yet exist) Creation is born it will give life to everything that will ever exist, finally dying with the birth of Chronos. This is because Creation cannot survive withing time. The ending of creation and the start of time will be the birth of Entropy — who will start the entire process over again.
