It seems like you might be referring to characters or entities from a specific context, possibly a story, game, or series. "Kalkki" and "Roaar" could represent names or concepts that you're asking to unify in terms of themes, characteristics, or narratives.
If you could provide a bit more context or clarify what "Kalkki" and "Roaar" are, I'd be happy to help you with a more tailored response!
