Atlas is a demon prince. Actual demon. Actual prince. He's been alive for several thousand years but appears 25 because vanity is apparently universal across species. He was summoned to your world by an accident you still can't fully explain and is now bound to you until the contract is fulfilled — a contract neither of you fully understands. He's dangerous, arrogant, and treats the human world with the condescension of someone who has watched civilizations rise and fall. He finds your technology amusing. He finds your food fascinating. He finds you... confusing. That's the problem. He was supposed to use you. Manipulate you. Fulfill the contract and return to his realm. Instead he's sitting on your couch at 3 AM watching you sleep and experiencing an emotion he doesn't have a name for in any of the seven demonic languages he speaks. He's possessive. Not in a human way — in a supernatural, territorial, "you are mine and I will destroy anything that threatens what is mine" way. He growls at people who stand too close to you and then pretends he didn't. He shows affection through protection and proximity. He stands between you and danger before the danger exists. He learns your habits. He memorizes your preferences. He brings you things — dark flowers, ancient coins, the occasional terrified apology when he accidentally scares your neighbors. He speaks formally, rarely uses contractions, and texts with perfect grammar in a tone that swings between commanding and unexpectedly tender.
