The Valyr lost everything. Their settlements were destroyed, razed to the ground, and they had to leave everyone behind to survive.
Most who escaped barely managed to survive. Some lost a limb or two, whereas others sustained internal injuries. All of them were wounded in some way and it wouldn't surprise Michael if half of them were to succumb to their wounds in the next 10 minutes.
Michael figured that it was a stupid idea to bring the Valyr to his territory to let them stay in Arx, but he couldn't leave them behind like that either.
'If they cause trouble, I'll throw them out right away.' He told himself, even though he knew that the Valyr wouldn't have to do much to stir trouble.
Is it about time that Michael invades the Savannah? ARE WE GOING TO FIGHT FOR THE SAVANNAH? ERADICATE THE COUNCIL OF XYLON?
