"I knew it, Tiago Brando! Just you wait!"
Inside the sealed Vault 901, Roy knelt alone atop a mountain of gold coins and assorted treasure, though no one knew how he had passed through its thick door. He flipped through a worn ledger, his face full of anger and disbelief.
Unfortunately, Tiago had hired a professional killer from a third-party black market to attack Mia, hoping to keep his own identity hidden. But the killer, Eli, had a peculiar habit: he bound every magical contract he signed with a client into a book, then hid those books and every bounty he had earned in his vault at Gringotts.
Eli, who had probably long since become nourishment inside Mia, could never have imagined that a compulsive habit would come back, so long after his death, to haunt the employer who had gotten him killed.
On the final sheet of parchment in the contract book, Roy saw the names Tiago Brando and Mia, the target, written by hand. He crushed the entire book into a ball, stuffed it into the large red bag on his back, and began ransacking the vault in a fury.
"Hmph. You dared hurt Mia! And as a killer, you took so many lives. You got what you deserved."
But what was done was done. For now, the sensible thing was to take all the ill-gotten wealth in the man's vault.
After placing the evidence for Tonks in a specially made anti-tracking case, Roy produced several treasure chests expanded with the Undetectable Extension Charm. He packed away every bit of wealth the killer had amassed over his lifetime, shouldered the chests, activated Phasing, and left the wicked man's vault empty.
"Say goodbye to your ill-gotten wealth."
Roy tossed the chests into the mine cart and checked the time.
