I like the name, I'm not sure if you did in on purpose, but it can be seen as a reference to two mythological beings also called Dis:
- Dís: A ghost, spirit or deity associated with fate who can be either benevolent or antagonistic towards mortals. Dísir may act as protective spirits of Norse clans. Their original function was possibly that of fertility goddesses who were the object of both private and official worship called dísablót.
- Dis: a Roman god of the underworld. Dis was originally associated with fertile agricultural land and mineral wealth, and since those minerals came from underground, he was later equated with the chthonic deities Pluto (Hades) and Orcus.
So, both...ahem, fertile, but also deadly in both references. Fits her quite well tbqh.
