Here is a list of BA adoptions that you may choose from. Keep in mind these spirits/entities may come with very little information, may not speak very much and take time to get to know you, they have either been abandoned, stuck in something and left for centuries or looking for a specific type.
Could have decided that they were not a fit for a companion, I will let you know which one when you adopt, they will be chosen carefully. Spirit Adoptions gives a home to abandoned or otherwise homeless spirits. It is a free service that gives spirits a loving home.
Remember, you can only adopt 2 a month, you must have an application on file and it must be with purchase.
