Eresigender is a neurogender or xenogender specific for systems that have eresians. It is a gender that can only be described by eresians, since the experience of being an eresian in a system is so unique the gender experiences that come with it would be just as unique as the eresians themselves.
It can be used as a modifier or alongside other genders to help describe an eresian's experience with gender, such as eresigirl, eresiboy, eresienby, etc.
