Zechariah

Zechariah was a high ranking angel and the direct superior of Cassiel and a direct subordinate of the archangels, but after the fall of Lucifer and Gabriel fleeing, he served Michael and Raphael. He had been alive for over 6 millennia.

Like many of his angelic siblings, he supported the release of Lucifer so that Michael could kill him and Earth could be made into a paradise. After Lucifer was freed, Michael sent Zechariah to help Lucifer get his vessel as Michael already had his. Nathaniel and Raziel tried to stop Zechariah and Lindsay was brought along as she begged Nathaniel to let her help. Zechariah was killed by Lindsay with his own angel blade.
