Some time around 151 AG, Senna had become acquainted with Tonraq, who had been banished from the Northern Water Tribe. She fell in love with the ex-general, whom she later married, and by 153 AG, she gave birth to their only daughter, Korra.
After they found out that Korra was the Avatar, Senna and Tonraq requested the presence of the Order of the White Lotus in 157 AG to ascertain that fact officially. After the White Lotus leader voiced the abundance of prior false claims about the Avatar's identity, Senna proudly stated that their search had come to an end. When the leader skeptically questioned her confidence in this claim, Senna called out to Korra, who immediately burst through the wall, proving her bending prowess to those present in the room.
