Rees’s Purpose
Rees serves as a moderating voice—a “good devil on Warner’s shoulder”—offering conflicting perspectives and extra insights to counterbalance Warner’s more extreme impulses.
Rees’s Profile
He is a passive, nurturing Gatekeeper who avoids radical actions. However, he is prepared to forgo his Gatekeeper duties if circumstances become too severe.
Background
Not much has been revealed about Rees. We do know that, in Season 1, he is a loyal and conscientious Gatekeeper under Warner’s command. He works diligently despite the strain of Warner’s aggressive and unpredictable behavior. Rees resides in Archeston with his wife, where he is currently based.
