Titania, being called the "Forbidden Planet", is the only stage in all of Star Fox 64 to not feature any of Andross' forces. Instead, all of the enemies and defense systems, including the boss Goras, are said to be remnants of an ancient alien civilization, with Goras being said to be a bio-weapon the ancient people modified before they went extinct. The official Japanese Star Fox 64 guide (as well as the Star Fox 64 Official Player's Guide) hints that the underwater ruins seen in the oceans of Aquas are connected to the ancient ruins on Titania.

As it did for Bacoon and the underwater ruins of Aquas, the Star Fox 64 Official Player's Guide would expand upon Goras' and Titania's backstory, claiming that it was formerly a green lush planet, and that the ancient people who lived there were an advanced agrarian civilization that would leave behind their harvests at temples that existed in each town to appease Goras. It claims that the civilization was destroyed by an asteroid colliding with Titania, leaving Goras as the only surviving creature on the planet that was now a barren wasteland, and it also claims that it was modified by Andross.
