Lili Hamilton

Chief Faculty Researcher for ARM University at Dometown, she is one of their lead Triume along with Angelus Andrews (and ?).
She recently took an interest to the Team in general and Tatum in particular (well, he pursued her for a bit, at first). While taking Kevin Hart to Minos Base to be interred following his part in an assault on some dignitaries, she converted to Lumina and now views Tatum as something of a mentor.

Secret Lovers?

It's not really known, but Tatum and Lili have... something? going on.
