" Pan hated seeing people die, because of what happened to their dæmons: they vanished like a candle flame going out. He wanted to console this poor creature, who knew she was going to disappear, but all she wanted to do was feel a last touch of the warmth she’d found in her man’s body all their lives together. The man took a shallow, rasping breath, and then the pretty hawk dæmon drifted out of existence altogether. "

― Philip Pullman , The Secret Commonwealth (The Book of Dust, #2)
