Hearth

UNIQUE was asked by the nations with a claim on the Arctic Circle to investigate a meteor impact displaying unusual gravitic and temporal energy readings. They secured and transported the meteor—a large obsidian sphere—back toward the Geneva base for research when the sphere hatched like an egg en route. The being that would eventually be known as Hearth assembled itself from the fluid within.
They (Hearth’s preferred pronoun) seemed capable of communication, but did not have any memory as to their own background or any reason for crash-landing on Earth. Lacking anywhere else to go, Hearth has since remained with UNIQUE and assisted in their missions. The alien construct finds Earth and its people fascinating, and spends much of their time learning more about this planet.
Hearth appears to be a sentient energy being capable of manipulating kinetic, gravitic, and temporal energies, and is contained within a number of linked spheres and ovals approximating a round, humanoid form. Their eyes glow a soft, warm red, and the combination of their appearance, amiable nature, and love of creature comforts—blankets, comfy clothes, and warm rooms even though they do not strictly need them—led to the rest of UNIQUE naming them Hearth.
UNIQUE is still researching what Hearth is and where they might have come from—both to help the alien return home and to ensure the strange being doesn’t foretell an approaching danger. For now, both Matron and UNISON are confident that the entity themselves does not represent a threat, and is even useful in helping promote global peace and safety. Despite their existence as an apparently technological entity, Hearth has shown the most affection for the ever-optimistic mage Blackberry, and seems wary of El Rayo and his engineer's curiosity.
