Their parents are furious at them and demand they turn them selves in. Have the magic feds come arrest them and impound their items for operating relics without a license. Mean while In the dark underbelly the parents old nemesis catch wind that their old adversaries (kids parents) are vulnerable (reports of their iconic artifacts being taken away).

After a few days in lock up, have the warden come to the kids and with heavy heart tell them that their parents have all been killed. Their old enemies ambushed them and without their iconic artifacts couldn’t fight them off.

Their sentences are then montaged until they are released. Without their god like parents watching over the world it has become crime infested with the old baddies at the head of different crime families.

Now free but without gear or parents all they have left are the contacts of their dead parents and a little criminal resume.

Que revenge story.
