Elsewhere in the spiritual world, Aeress was hard at work trying to regain herself without any issues. Because the abyssal entity only inhabited her body and was yet to fully acclimatize to it, even if it eventually did, killing its physical body would not kill its soul. It would surely damage the soul, but it would live on. At the moment however, Lodestar had forcefully disassociated the abyssal entity's control from the body and broken its link to it. If it wished to take control again, it would have to reestablish the connection.
For now, Aeress just had to be quick and inhabit her body before it was too late. To do that without any attachment to the abyssal entity, she followed through with her plan.
Utilizing the souls that had been provided, she was able to burn them as energy to facilitate the process, binding her soul to her body perfectly, making it entirely hers.
