Erica was a woman with a rather courageous and strong personality. She wouldn't think for a second before choosing an option that would risk her life. She was ready to give up her life if it meant that her sect and her daughter would be safe.
Her sect and her daughter were her weaknesses that Azaroth took complete advantage of. However, Azaroth had overlooked that these two things were her greatest strength. They were the source of her conviction.
To protect them, she was ready to do anything. Thus, she was ready to take the risk to protect her sect and her daughter from the King. When weighing the risks, she felt that the threat she felt from the King was much greater than Azaroth.
Thus, she began to create countermeasures in case the contract takes effect when she mentions Azaroth to the King's envoys. She created files and also implanted some of her memories within a few objects that described just how dangerous Azaroth was.
