Sold to the Devil (слэш)

Canon Divergence. Obadiah Stane still sells Tony out the way he does to the Ten Rings, however, the Ten Rings (before they get blown to smithereens) and Stane make another deal to get rid of him and earn a bit of money. They sell him to space slave traders so he’ll be a profit that will never annoy them again. Tony gets grabbed and shoved into such a life, but he isn’t an easy slave to control; he’s sharp and broken and smart and he keeps escaping, pissing off the ‘owners’ who buy him so he gets sent back with another few bruises and scars. But Tony is learning and constantly planning. He won’t be a ‘slave’ for long.
He’s still doing that x amount of months into his slavery when Thor, Loki and the Warriors Three are on the same planet as him - where the slave trade is accepted and prevalent - and Loki, known for strikes of “whimsy” that no one understands, buys Tony.
