Romana I

Played by Mary Tamm

"You're capricious, arrogant, self-opinionated, irrational, and you don't even know where we're going!"

Romanadvoratrelundar was a Time Lady, assigned by the White Guardian to help the Doctor assemble the Key to Time. Younger than the Doctor by many hundreds of years, but academically smarter, Romana was initially haughty and dismissive, but she grew to enjoy her travels in the TARDIS and respect the Doctor.

On Tara, after finding the fourth segment of the Key immediately, she met her double in Princess Strella, and was nearly married off into the royal family. Later, she was staked out by the Swampies as a gift to their giant octopus god, Kroll, before the Doctor rescued her.

After being tortured by the Black Guardian’s agents, she saw the key successfully reassembled, and balance restored to the universe. She then decided to regenerate, and take on the form of a woman she had recently met - Princess Astra of Atrios.
