Omega hovered before Hermione Granger. Between them rested two boxes labelled "A" and "B".

"Do the boxes have any special powers beyond modifying my Muggle bank balance?" Hermione asked.

"No," Omega said.

"Where do you get the money?" she asked.

"What do you mean?" Omega said with mock incomprehension.

"Fiat currency is a zero-sum agreement between human beings. It is not a physical thing. You cannot conjure one half of a mathematical equation out of nothingness. For you to have a million dollars, a human must have given it to you," Hermione said.

She opened opaque envelopes #4,7,10. £3 pounds were deducted from her Muggle account. Hermione opened the empty opaque envelopes #3,5,6,8,9. Hermione burned transparent envelopes #4,7,10.

Hermione flooed to Gringotts the next morning where she confirmed the transactions with her account manager Chauna. Together they identified the highest-vega security that could be traded on time-horizons of one hour. Hermione gave opaque envelopes #11-#20 to Chauna and inst...
