 Eddie saves Tower from a beating, and convinces Tower to sell the land to the ka-tet in the guise of the "Tet Corporation".Tower is an extremely reluctant recruit to the Ka-tet's cause, and his selfishness, obsessive addiction to acquiring rare books nearly derail the Ka-tet's efforts on several occasions.His eventual—and reluctant—decision to do the right thing comes largely thanks to the influence of his much more selfless, heroic friend, Aaron Deepneau.
