Will Neville had many disciples after he left the Church and they learnt Celestial Spirit Magic from him. His disciples carried out a Biological Link to prevent the Infinity Clock from being completed. After this, Will Neville suddenly became an author and joined public life once again. After Will Neville died, his disciples dispersed and their whereabouts were unknown.
