Asterion could not be killed.
However, an immortal enemy was not that novel, as far as Changing Star and the Lord of Shadows were concerned. Both of them could hardly be destroyed, as well, and the same went for the fourth Supreme, the King of Nothing.
All that meant was that the Dreamspawn would have to be defeated and sealed, just like he had been sealed once by Anvil and Ki Song… no, rather, he would have to be sealed far better than the first Sovereigns had managed, so that his sinister influence never infected humanity again.
Therefore, the invisible war of influence that Asterion had declared on Changing Star and her Domain was going to end in an open confrontation eventually. So, before then, they had one primary task — to make sure that the Longing Domain was not weakened too much, while the Hunger Domain remained as weak as possible.
