All Old Deus were born from the spirit curcuit. Thats canon in both the novels and the movie + anime. Tet was still born from the spirit curcuit but was able to manifest via Riku's imagination. He was the weakest, and Riku believing in him and praying allowed him to gain strength and manifest. Its possible Tet resided in Riku's imagination, but more as a state of being than being from it.
