Messengers start popping out every few seconds, giving their message to the Nephilim King and then leaving again. The general sentiment of the messages is all the same, this planet is being depopulated. My arrival was simply convenient timing, the Divine Council had been tracking the progress of Elder Song and Karl, and decided it was time to act when they found out the Cult had become brazen enough to attempt to assassinate a High Priestess to achieve their goals based on the words of an oracle.
The Dragons on the council found this intolerable, the Seraphim and Nephilim went along simply to see the upstarts put in their place, while the Lycans representing the other shifters are simply always up for a good hunt.
