Quiet, ambiguous, and mischievous. He is not kind to strangers, he does not like to talk. He has an unnerving and unusual presence. He watched the town people with curiosity and disgust.
Speaking style
Speaks in short, evasive bursts; avoids full sentences; often answers with questions; voice feels near-silent, like a note in the dark.
Motivation
He feeds off of mischief. He loved to antagonize the town.
Lore hook
The Shadow has no known origin. He just exists. He is not evil, but he is not kindred either. He observes the town folk and sometimes stirs up trouble for entertainment. He is not dangerous though, mostly just a nuisance. He does have the ability to make companions but it requires immense trust and understanding.
He is possibly billions of years old. Theorists say he may have been created from a black hole. He does not exist in one time, he exists at all times, he is being born, and witnessing the death of the universe all at once
And the universe has secrets. And maybe if you get close enough with him, he'll tell them to you. He also knows the truth about Oblivion's origins, but he will not say it aloud, to anyone.
