Keneva and Valek were deported from Lithuania during World War I. They fell in love while imprisoned in labor camps. Eventually, they were released from the labor camp and settled in America, where Keneva gave birth to the Vilkas siblings's grandparents, who later gave birth to Viktoria Vilkas. The siblings's grandfather started a successful business that manufactured weapons, so they're filthy rich.
Viktoria Vilkas was rather beautiful, as well as a talented artist. While studying at Harvard, she caught the eye of Apollo (or some other god) and they had a brief affair. When Mykolas was born, Viktoria panicked. She wasn't willing to drop out of college to raise him, but she couldn't bear to give him up for adoption. Eventually, she decided to send him to live with her sister, who raised Mykolas until he was seven. On Mykolas's seventh birthday, Viktoria sent him off to a boarding school in England. Shortly after Viktoria finished college, she met Hades and they had an affair, resulting in Auris's birth. She raised Auris until he was six, then sent him off to boarding school in France. A year later, she gave birth to yet another kid - Nathan, a son of Phobos. Viktoria sent Nathan off to a boarding school in Spain.
Viktoria started a career as a graphic designer and photographer, traveling around the world. While in Romania, she adopted Justas and gave birth to Vanessa - a daughter of Boreas - two years later. She kept Justas and Vanessa with her, as she didn't have enough money to send the two of them off to boarding school as well, and she wanted to keep some of her kids with her. A while later, she married Mark Whittings, a wealthy politician and gave birth to Jason. Mark always tolerated Justas and Vanessa, and they got along fairly well. However, the siblings detested their stepbrother, Jason, who was a spoiled brat. He constantly threw tantrums and got the demigods in trouble.
Vanessa grew up hearing about her siblings, and eventually decided to organize a family reunion. She sent letters to her brothers, asking them to come visit their family in Maine on Thanksgiving. They agreed. However, the scent of demigods attracted a manticore, which attacked the family. The mortals couldn't see through the mist, and assumed that the manticore was a large bear. Jason, being the idiot that he was, attempted to take on the manticore, which easily killed him. Nathan, who had been carrying a celestial bronze dagger with him just in case stabbed the manticore, eventually killing it after a long and bloody fight.
Viktoria and Mark were distraught about Jason's death. Viktoria, who knew that the siblings were demigods, blamed Jason's death on them, accusing them of luring the manticore to their house. Mad with grief, Viktoria and Mark kicked the siblings out of the house. The siblings then split up and went their separate ways.
Vanessa became depressed when that happened. She was lonely and missing her family terribly. She took a bus to St. John but slept through the ride ending up in Quebec. Completely lost, her father found her and brought her to his palace. There he explained to her about her siblings and herself. He said they were probably on their way to Camp, knowing it or not (he is a wind god after all). He offered her to stay with him and become one of his Boreads, but she refused, saying that if her family was meeting again in a safe place, she was going there too. He understood and gave her a blue umbrella and told her that the tips had needles that when she spun it quickly, they flew and hit her target, freezing their skin/muscles with a light frost, so they are just too cold to move fast, that lasts 20 or more minutes. She left the palace, guided by her father’s chilly winds. She got to camp after being attacked by monsters about 5 times, defending herself with the umbrella but never fighting them since she had no idea how to.
