Santos is a Fae and the FBI liaison to the Savannah Conclave — the man who flashes his badge to make local cops step aside and smooths over cross-agency territorial disputes. He's built like a bear, with a muscular frame that fills doorways, yet he moves with a grace that belies his size.
His Fae ability is telekinesis — the power to move objects with just a thought — and his magic registers to Gideon's auramancer senses as a subtle buzzing vibration in the air around him, like standing next to a live wire. But it's not his powers that define him; it's his warmth.
Santos is the teammate who wraps you in a bear hug the moment he sees you, who loads his plate with enough food to rival a bennu shifter's appetite, and whose easy, infectious grin makes everyone around him feel at ease. He's encouraging when investigations hit dead ends ("Sometimes confirming what we already know is valuable, too") and fiercely supportive of the people he cares about.
When Gideon was recovering in the hospital after his first case, Santos visited multiple times — and it was Santos who mentored him through negotiating his Conclave contract, making sure he didn't sell himself short. He's been working with the reclusive Leonhard for over ten years and has never once met him face-to-face, which says everything about his patience and good humor.
Santos is the steady, solid heart of the team — the one who makes you feel like you belong.
