Twig is a roaming firemaker encountered during The Firemaker's Curse. He is a timid man, often stuttering and afraid of everything. He was born in Lumbridge and only recently left in an attempt to become braver, after his parents encouraged him to become a firemaker to combat his cowardice. Part of his transformation included taking the nickname Twig, which he later realised was maybe not the best choice.
It is possible for Twig to die during the quest. If he survives, he joins the surviving firemakers at the Circus. He has a flaming poi dance named after him, Twig's Try.
