In The Magicians Season 4, Quentin Coldwater brought magic back by making the ultimate sacrifice -- but, as it turns out, that worked a little too well.
The Season 5 trailer picks up with Julia, Alice, Eliot, Margo, Penny and their friends mourning Quentin's death. However, they quickly realize something is off. As Dean Fogg succinctly puts it, "There's too much goddamn magic." Unfortunately for them, this imbalance has triggered the apocalypse, and they're the only ones who can stop it.
According to the Season 5 synopsis,
Last season, magic was saved, but at a terrible cost: the life of Quentin Coldwater, who died heroically to save his friends— and the world. Julia, Alice, Eliot, Margo, Penny and their friends (and frenemies) must learn to navigate a world without him. Now, a new threat has arisen: in freeing magic, the balance tipped the other way and there’s too damn much of it, and as the excess builds, an apocalypse looms. Can the magicians get their shit together to save the world without Q?
Returning on January 15 on Syfy, The Magicians stars Stella Maeve, Olivia Taylor Dudley, Hale Appleman, Arjun Gupta, Summer Bishil, Rick Worthy, Jade Tailor, Brittany Curran and Trevor Einhorn.
