The Entity

Appearance
The original form of the entity is unknown, though it assumed to have some kind of corporeal form given that it was able to be split apart. Whilst possessing Gabriel he is able to control the body but with visible awkwardness, at one point making an offhand remark that the bipedal body was "limited", however over the course of several hours started showing signs of adapting better to using the body, displaying more humanoid behaviour over time; much to the discomfort of the crew. It is notable that when possessed by the entity Gabriel's irises become incandescent, a trait that has been observed in another occasion by at least one of the crew.

Personality
The entity is somewhat characterised by a lack of personality, being seemingly driven entirely by pragmatism. There is some semblance of an ethical code that it adheres too, claiming to be attempting to right a disbalance within the universe though what is meant by this is largely unknown, only that there seems to be similar entities at work who have caused the apocalyptic event that is threatening the universe. It has shown minor concern for the crew when allowing Gabriel to retain control of his body, warning them of his ferocity, however it is likely that this was an attempted act of self preservation rather than genuine interest in their wellbeing.

Biography
At some point in time the entity was divided, how and when are unknown but the entity's relation to time and space are apparently abstract, as when first encountered the entity was able to distort the crew's perception of time to fight back at them. The "fragment" of it that the crew encounter claims that it was stuck between universes, crossing in to theirs when their malfunctioning FTL drive temporarily moved them outside of space as this supposedly created a hole in the universe. It is holes like this in Gabriel's universe that are causing it to consume the crew's one in order to sustain itself; how literal this is up to debate as the entity states that it simplifies concepts for the sake of the crew's understanding.

The entity shows little need or want to do anything during its time on the ship, never sleeping or eating despite Gabriel doing both when not possessed. It has shown a strong dislike of the medical facilities, to which Gabriel ascribes a fear of silver. It also has somehow engaged in a fight with Gabriel and though this went unwitnessed it was evidently somehow physical, having caused damage to both the interior of the ship and resulting in Gabriel losing his left ring finger. It appears from this point onwards that it's control over Gabriel is waning.
