There's the familiar tug on Avery's soul, of a contract being sealed. This is the real deal. Tyzias takes the contract, tapping her metal arm, rolling it up, and gently tucking it inside an opening that seems made for it.

Tyzias's phone alarm goes off, signalling the start of the race. She casually strolls across the start line, and--

--teal runes engulf her body, and she's immediately a step away from the finish line. The contract hasn't been broken somehow, that would be easy for a man of Avery's caliber to sense. No. Whatever Tyzias just did is within the terms she laid out both online and on the contract.
