Determine how the character’s view of home changes throughout the novel and what factors cause that change.

First, home was the dimension in which the TT lived.

Secondly, the TT found a sense of home in certain people (creatures) he met along the way. He found feelings of home in places or people he expected to see. Namely, Weena.....

For, by merely seeming fond of me, and showing in her weak, futile way that she cared for me, the little doll of a creature presently gave my return to the neighbourhood of the White Sphinx almost the feeling of coming home; and I would watch for her tiny figure of white and gold so soon as I came over the hill.

I believe that eventually, the memories of Weena, we the things that lef him to disappear.
