Firestar is a trusted friend of the Doctor, especially of the 3rd. When the Doctor met him in his Second Incarnation, there was a plague going around, making the air deadly to anyone that breathed it.
The Third Doctor actually saw him as a very close friend, as he was exiled there by the Time Lords as punishment for treason. In that, Firestar was turned from a skeptic of aliens to a believer.
