M. Mather

M. Mather was a 21st century Human who worked as security guard in 2024.

In April, 2024, he worked at the Europa Mission pre-launch gala, securing the place and watching over the guests in the ballroom, along with his colleagues, including R. Chandler, A. Finch, and J. Hawkings.

Mather was in charge of the entrance, checking the ID bracelets of incoming guests when Cristóbal Rios arrived and tried to pass through. He was suspicious of Rios as his bracelet briefly registered him as "Karl Leonard Kelley", a sixty-year-old heart surgeon, but let him inside after Agnes Jurati cloned Rios' alias of Xavier Vincente Villalobos into the computer system.
