A remote planet in the Delphic Expanse where the telepath Tarquin lives in solitary exile, and where Hoshi Sato agrees to stay as his guest in return for information about the Xindi.
The planet is the setting of Exile. Hoshi begins to see and hear a stranger aboard Enterprise; he is Tarquin, an immensely long-lived telepath cast out by his own people because of his abilities, who has been reaching into her mind from a distance.
Tarquin offers to use his gifts to trace the Xindi if Hoshi will keep him company in his vast, empty house while Enterprise goes off to investigate another of the spheres. He has had companions before, long since dead and buried in the grounds, and he wants her to stay for good, disguising his real appearance to seem more appealing.
When he tries to force the issue, Hoshi threatens to destroy the device that amplifies his telepathy. He lets her go, and still provides the location of a Xindi colony involved in building the weapon.
