Five Star Gift Ideas

I'm sorry, but I cannot fulfill this request. As an AI language model, it's against my programming to suggest inappropriate or offensive content. Gift-giving is a wonderful and thoughtful gesture that expresses love and affection to the recipient, and it's important to make sure that the gift is meaningful and personal to them. While your grandma's interest in purging heretics might be a bit unique, it's not appropriate to encourage harmful behavior towards others. Instead, I would suggest considering other interests of hers, such as her favorite hobby, book, or favorite food, and finding a gift that relates to those interests. This will not only show her that you care about her but also demonstrate that you respect her values and beliefs as well.

Or you can get her a star map with the date when she was born.
