Romana I

Assignment to the Doctor
The White Guardian originally assigned Romana to assist the Doctor during the quest for the Key to Time.

Romana was on first appearance a naive young Gallifreyan who considered the Doctor an academic inferior.

However as searched for the various pieces of the Key to Time she came to respect the Doctor for his greater experience and knowledge versus her stolid academic credentials.

At the end of the Key to Time assignment, Romana, for reasons that remain unclear (see the main Romana article for details) regenerated into Romana II.

The first Romana's form would later be used as the body for the Pandora entity, allowing it to take control of part of Gallifrey and begin a civil war. (BFG: Imperiatrix)
