The Omitted are very insecure and untrusting beings. They can see everything in Foo except for themselves and their reflections. They are dependent on others to tell them how they look. They reside in caves and trees in the mountains outside the Invisible Village in the mountains above Fte.

Tosia is an Omitted. He has a run in with Brindle in the third and fourth books. Tosia questions Brindle about his appearence on their way to the Invisible Village. Tosia is said to have had his shoes on the wrong feet, a long brown beard and eyes "the color of chocolate".
