The second Archangel in the history of ever to be banished from Heaven. The reason for her Fall is....well, let's put it in the most basic way possible- Apocrythan got into her head again, forcing her to slaughter countless Angels. So many lives were lost....the other Archangels stabbed her with a flaming sword and sent her falling down to Earth, almost like a comet. When the other Angels realised that Lavenza's horrible crimes were not technically hers, it was already....well, I wouldn't say it was too late, necessarily, but....by that point, Lavenza had grown to enjoy quite greatly her new...."life". She had wrecked havoc on Earth, and didn't intend on stopping any time soon.
After failing (very miserably) to convince Lavenza to return to Heaven with them, the other Angels, with Mirrorial's help, manage to subdue her. Upon returning her to Heaven, the other Angels explained how sorry they were for not....well, for being so blind to the truth. Lavenza tells them that they can all go to Hell with their apologies, however, she realises that although wrecking havoc on Earth was(and still is) a favoured pass time of hers, she truly did miss her friends and family. And they missed her, too. But, she had too much pride to ever directly admit this, and so refused to stay in Heaven. However, Heaven was basically going to Hell, as without one of their Archangels to support them, everybody was just falling apart. It was complete and utter chaos, at every turn and corner.
Lavenza eventually agrees to stay in Heaven, although....the beginning is very rough, as many other Angels....well, aren't too happy to see her again. Many others are, on the other hand.
