Kranid
Kranid is a term that can refer to several different concepts depending on the context. In biology, a kranid is a type of skull bone, specifically referring to parts of the neurocranium. The neurocranium itself is the part of the skull that encloses and protects the brain. Different animals, and even humans, have various bones that collectively form this protective structure.
In a broader, non-biological sense, "kranid" might also be used colloquially or in specific fictional contexts
