The Sentinels burned away to ash

"Deirdre!" she had screamed, over and over, until her throat had gone ragged and her voice was hoarse. There was no going back on her commitment to Drageda, for her safety net— her very heart— was gone. Some of the tall giants remained, their bark merely blackened and scorched, but others had burned at their bases until they were weak enough to fall. If any wolves of Donnelaith had survived, they were no longer here, but Emaleth could not catch her twin's scent— not even at their father's grave— and the dark witch lamented.

She had dreamed of this, but dreams were merely dreams; a projection of one's innermost anxieties and turmoil. But it had turned to reality, and as Donnelaith had, her heart had burned away to ash.
