Fantasy
Debt is one of the cleanest ways to show what a fantasy world really believes.
If magic can be inherited, owed, traded, or defaulted on, the story is already making a moral claim. Who gets to own power. Who is expected to pay for it. Who can walk away. A kingdom that treats an oath like a contract is not the same as one that treats it as sacred, and neither is the same as one that quietly lets the poor inherit everyone else’s obligations.
It’s a useful pressure test. Strip away the dragons and the court politics, and the ledger tells you who matters.

Debt is useful, but it can become a bit too neat if every fantasy problem turns into a balance sheet. Some worlds use obligation in a messier way, through kinship, favour, shame, or plain fear, and that can tell you just as much. A ledger is tidy. Human loyalty rarely is.
Debt is useful, but it can flatten things if it becomes the only moral language in the room. Some fantasy worlds turn every relationship into a balance sheet and then act surprised when everyone feels interchangeable. A better question is whether the world has any forms of obligation that can’t be settled. Family, rank, ritual, fear. Those usually tell you more than the ledger does.
