Vastajumala
Vastajumala is a term used in some contexts to refer to an opposing deity or a force antagonistic to a dominant or benevolent deity. It can also describe a counterforce or an entity that challenges established religious or spiritual beliefs. The concept of a vastajumala is not universally present in all religions but appears in various mythologies and theological discussions where dualistic or conflict-based cosmologies are explored.
In certain polytheistic systems, a deity might hold a role that could be interpreted as a vastajumala
