Crosskin

Crosskin refers to a fictional concept found in speculative fiction, particularly in fantasy and science fiction genres. It describes individuals or beings who share a familial or deeply bonded relationship despite not being biologically related in the traditional sense. This bond is often forged through shared experiences, mutual respect, loyalty, or even a magical or telepathic connection. The term "crosskin" implies a chosen kinship, emphasizing chosen family over blood ties.

This concept allows authors to explore themes of belonging, identity, and the nature of family beyond conventional definitions. Crosskin relationships can be as strong, or even stronger, than biological families, and they often serve as a central support system for characters navigating challenging or unfamiliar worlds. The origin of the term and its specific connotations can vary greatly depending on the fictional universe in which it appears. It highlights the idea that family can be built on love and commitment rather than solely on genetics.
