===Fallen Angel===
The most popular line of thought One theory is that the comet is in fact is an [[Angel]], or even an [[Archangel]] who has been expelled from the [[High Heavens]] for unknown reasons , and that hitting such an angel may have impacted or been made to impact [[Tristram Cathedral]] is either as a sign , perhaps to call the hero characters draw heroes there, or random chance. The reason for this line of belief is the This theory may be supported by concept art , which may show the meteor with an angel-like appearance. The [[Tyrael]] and [[Izual]] are two most popular candidates are , who may have been banished by the [[TyraelAngiris Council]] and for too often interfering with the [[IzualSanctuary]].
The Angels and the High Heavens Below are by no stretch "good" creatures. In [[Sanctuary]], there is no true good force. Even the Angels, and Tyrael himself were once in favour of eradicating the humans and the whole world. What sort of internal politics, could have made them expel one of their own to our realm is unknown, but it could be related to Tyrael or Izual interfering with the world of humans once to many for the [[Angiris Council]] These are the concept art pieces that have been speculated to be related:
