Ehr Tano is the mother of Marcel Tano and Lydia Ericson, the widow of Bruce Tano, and the wife of Karl Ericson.

Ehr was born in 495 GD to parents Marcus Lora and Genevieve Lora, in Edicu, Teth.

She was orphaned at a young age after a house fire killed both of her parents, and she was the only survivor, being passed from an opening in the burning wreckage into the arms of a firefighter by her father. He tried to pass Genevieve through the opening after Ehr, but the house collapsed at that moment, trapping them inside.

She was adopted by Bruce Tano in 499 GD. He paid off the orphanage clerk to destroy any record of her being there. He isolated her inside his home, prevented from ever having contact with other children her own age, and ensured he was the only person she ever saw. He began molesting her when she was nine years old, and continued this for years, only stopping when she got pregnant at the age of 14.

Ehr gave birth to Marcel in 510 GD, at the age of 15. Bruce's savings were no longer sufficient to support two children, so he found work as a police officer. His now-frequent absences from the home gave Ehr a rare opportunity to leave the home and explore her neighborhood. Bruce had instilled her with a deep fear that she was astoundingly ugly, and that people with a face like hers would be killed on sight by “the ones outside”, so Ehr heavily disguised herself during her outings with Marcel.

These outings are when Ehr discovered that she had a talent for storytelling. Ehr would bring an infant Marcel to a nearby park in Tolikra, which they were within walking distance from, and tell him stories she would make up as she went. She continued this for a year, until she was eventually caught when Bruce was sent home early on paid administrative leave after brutally assaulting a jaywalker. After he nearly choked her to death one evening, Ehr fled the home. She stole several hundred Mun from a safebox, and applied for the draft in GD 511, as the Adenian-Tethish War was at the time well underway. She realized at the recruiting office that she had forgotten a disguise, and worried briefly that she was about to be executed. She was shocked to learn that, as it turns out, Bruce had lied about everything.

As the need for fresh bodies to send to the front lines was mounting by the second, Ehr's information was not verified against any database or official records (of which there would have been none), and Ehr was put through basic training and sent overseas merely three months later. Ehr, as it turned out, was a fantastic shot, and a model soldier, and within half a year (due to the extremely high mortality rate at the front lines) she was promoted to Sergeant. During her time in the army, she very rapidly realized that she had been groomed by Bruce, and that Bruce had lied to her. But, regardless of that, she missed Marcel terribly. Her conflicting feelings about her living situation back in Aden came to a head when she was ordered by her C.O. to lead her fire team into a village known to house the wife of one of the enemy officers, kidnap the wife, and use her life as a bargaining chip to get the enemy forces to withdraw from the area.

Ehr could not follow through with this order, and she deserted her fire team under the cover of night, found the wife herself, and warned her of the coming threat. Ehr then escaped from the village wearing a set of that woman's clothes, bringing only her helmet and her rifle with her. She found work as a mercenary, defending trade convoys around Pealavy from assault by Adenian troops. Eventually, however, the war ended, and with it, demand for her services as a mercenary. With the conflict over, and her savings dwindling, Ehr made the difficult decision to return to Aden. She knew she could threaten Bruce with legal action if she needed to, and she missed her son.

She returned to her former home in 516 GD to find that Bruce still lived there, and to her relief, so did Marcel. She made clear to him that she was there for her son, and that she wouldn't tolerate the way he used to treat her. He initially agreed to this, but protested when she was no longer willing to have sex with him. Eventually, to Ehr's shock, Bruce confronted her about her desertion of the Adenian Army during the war. An act which, if discovered, would be branded treason, and lead to her execution. He proposed a compromise. They would be married, she could live her own life in the public eye, but she was not allowed to bring anyone into his home, she was not allowed to tell anyone that he had groomed her, and she was not allowed to pry into his private life. Ehr agreed to this, as she could see no other way to be allowed to raise her son while avoiding the consequences for her desertion during war-time.

Marcel, by this time, had met and befriended Rimas Nolie, and the two of them would often play “wizards” together under Ehr's supervision. Bruce, however, once again came home early one day and found Rimas in his home. He was furious that Ehr had broken their agreement not to bring anyone into his home, and while Ehr initially protested “I thought you meant other men!”, she was forced by the threat of being reported to the authorities for desertion to forbid Rimas from entering their home again. Rimas was initially disturbed by this, but decided that Marcel could just come over to her house to play wizards instead.

Ehr continued to play the part of doting stay-at-home-mom until Marcel was 15, in the summer of 525 GD, when Bruce was murdered. Believing that her cover had finally been blown, that Bruce had gone off to report her desertion only to be killed for sheltering her for so long, Ehr fled the country and returned to her homeland of Teth.

Ehr, upon arriving in Teth again, soon found work as a vampire slayer, as Eranz the vampire was spreading his influence in the area of Ehr's birth. Ehr killed many of Eranz's progeny in this line of work, earning his hatred.

It was in this line of work that she met her husband, Karl, and had her second child Lydia in 526 GD. In an act of cruel revenge, Eranz turned Lydia into a vampire in 542 GD, forcing Ehr into the impossible choice of either killing her own daughter, or allowing her daughter to live while Lydia killed innocent people. Ehr could not choose, and resorted to locking away her daughter.
