Sensei Seaworth is an NPC who can be found on Tuai Leit just south-west of the bank in The Arc. Players may aid him in collecting kami. He runs a shop called Spirited Away, where players can sell kami for chimes.
He plays a minor role in Tuai Leit's Own, advising the player on what is causing Ekahi's condition, dismissing the possibility of mental illness and suggesting it may be a mystical illness and to speak to Sojobo on Waiko instead.
When led to him by a master clue scroll, Sensei Seaworth will provide a towers puzzle scroll to complete.
