Arcadia LaVelle, powerful science and tech mogul. She's the main antagonist of the series, and she is up to some crazy, trippy, nefarious things that we'll learn more about as the show progresses.

She's also Chloe's mother, though her parenting leaves a great deal to be desired. She's very cold and distant towards her daughter, and usually when she speaks to her, it's to complain that she's not the daughter she wishes Chloe were. She holds both great resentment and suppressed longing for Trent, as well. Happy to see him again, but still filled with hurt over how they left things when they were young lovers.

Truth be told, Arcadia is a monster, obsessed with pursuing her goals at any costs. Whether or not there's any hope of redemption for her is one of the key questions of the series.
