The Inventor
Age: 26 (at time of story)
Background: Former Rice University engineering student (dropped out)
Marcus Delacroix saw the world as a series of inefficiencies waiting to be solved. Even the Water Wall behind the Galleria—sixty-four feet of cascading tourism—registered to him as thirty percent energy loss through heat dissipation.
He dropped out of Rice because the curriculum didn’t include what he wanted to build. What he wanted to build was something impossible: a way to give his sister back the memories she’d lost.
The Accident
Two years before meeting Kale, Marcus’s parents were killed in a car accident. His sister Lena survived but suffered severe hippocampal damage. She lost the ability to form new memories. Worse, she started losing the old ones—their childhood, their mother’s face, the knowledge that Marcus was her brother.
Echo was born from that loss. The technology that would change everything began as a desperate attempt to save one person.
The Partnership
Marcus knew code. He knew neural pathways and emotional encoding. What he didn’t know was distribution—how to get a revolutionary technology into the hands of people who needed it.
Kale knew distribution. He knew community trust and grassroots networks and the specific ways that word spreads through Fifth Ward parking lots and barbershop debates.
Together, they were complete. Together, they were dangerous.
The List
Marcus kept a handwritten list of every person harmed by Echo technology. Forty-seven pages of names, dates, symptoms. Each entry a person they’d tried to help who’d been hurt instead.
“Someone has to count the cost,” he said.
He never stopped building. The guilt never stopped growing. And in the end, he built something even more powerful than Echo—a device that could transfer consciousness itself.
He called it Unavailable.
“You can’t subtract suffering. One person helped doesn’t cancel out one person hurt. They just exist. Parallel. Unresolved.”
