Harper Jay Rook is an intrepid explorer documenting their exploits in the horrifying world we are currently calling "The Darklands" or "The Cryptid Realm". Those are placeholder names for now though. Harper Jay is a changeling with an academic personality, but has the energy and enthusiasm of a classic explorer. They're a young scholar who would later be one of the most prominent names in cryptozoology. They are a recurring role, and not directly related to Edmund and Quincy's adventures. Their perspective will be more like an audio journal and they will often be used to give background information on cryptids that Edmund and Quin will be interacting with. They are also very important for the overall lore.

As previously mentioned, Harper Jay is a Changeling. They don't have a specific gender due to their natural ability to mimic the form of other creatures, regardless of gender. Therefore, Harper Jay should sound androgynous, but they trend towards a more masc-leaning voice (He/They pronouns). They are softspoken, intelligent, and fearless. They also sound youthful, but should be unmistakably mature and confident. They won't be heard in episode 1, but they will be a leading role in episode 2.
