A weary, drink-sodden dwarf train conductor whose looping memory and magic gold coins reveal the trains' secrets — killed by a trap.
Vernon is the yellow line's dwarf conductor, met drinking in the employee break room on The Iron Tangle. Charmed by Princess Donut, he becomes the party's richest information source: he explains that employees black out at station 435 and wake at the yard, that the train physically resets each loop (letting him hoard duplicating gold coins and a drawing of a "wife" who does not exist), and that engineers only emerge in a derailment. His tragic arc ends when a booby-trapped reward-room suitcase unleashes Literal Fire Ants that immolate him alive as the party flees.
A weary dwarf in a wrinkled conductor's uniform, perpetually nursing a jug of moonshine, with a long healed scar down one forearm.
