At some undisclosed time the Phoenix Force came to Earth and created the "Burnt Place", a permanently razed clearing which was used by the xenophobic surrounding tribes of the Stone Age, to sacrifice anyone who deviated in any way from their norms. The Phoenix eventually came to Earth where it used a primitive female red-haired human to be its avatar. Using the nickname "Lady Phoenix", she joined the time period's incarnation of the Avengers. Her only known fight was with an out-of-control Celestial called the Fallen. It is believed that during this time she and Odin shared a romantic relationship that Odin considers as the one time in his life when he truly felt alive.
