Tolya Yul-Bataar

Tolya is a Grisha tracker and scholar who joins the hunt to find Alina Starkov, working alongside his twin sister Tamar. Calm, watchful, and formidably capable in a fight, he carries himself like someone who has survived on skill rather than luck, and who reads a room before he ever draws a blade.

Lewis Tan gives Tolya an unhurried confidence that makes him instantly trustworthy in a story full of liars — he's the rare character who seems to know exactly how good he is and never needs to prove it. The show pairs his physical competence with genuine curiosity about Grisha lore, letting Tan play intelligence and menace in the same breath.
