Galina Voronina is the Russian Master Assassin Bishop sends to London as backup in Assassin's Creed Syndicate's modern-day story. She arrives to help Shaun and Rebecca recover the Shroud of Eden and is set on killing Juhani Otso Berg.

She kills the whole team on her own and opens an escape route for Shaun and the wounded Rebecca, leaving Berg alive.
