Whims of a god

What can be more opposite, than an outcome from a crucial event going horribly wrong. One where luck didn't shine as hard, where timing was just a little off. Where the owner of his soul becomes someone else. One he hated, wanted dead. One he feared.
An outcome, where they're stripped of freedom, of dignity, forced into a situation and body they don't belong in. No resistance, no arguing, not even pleading will get any leeway from his whims. And there is no escape either - Even dying will just return their soul to the god.

Time slowly erodes everything, and eventually, it becomes nothing more than a glorified toy, a husk with a rotting core. Laying limp in the ruins of a forgotten castle, until the god returns to satisfy his next craving with his object of obsession.
Watching everything pass with a blank stare, until corruption takes mercy on its existence.
