I know i'm kind of late, but i want to have more details about the contract. What exactly happens when the contract is forged? What benefits are gained? Are there any downsides?
I think I've posted about this in other SocMeds (Tumblr, Twitter) as also asked by others-
Basically, you can ask Jester to fulfil your desires. Want the throne? Want to kill people? He'll do it. If he's lazy or thinks it's no fun... he might not.
In exchange, he can have your soul 'when the time comes' (as implied in the game). In their world, demons can't just take people's souls without a contract, and that's why he has to fulfil the contracted's desires.
There is also another upside for the demon, and downside for the human... but I'll keep the rest of the details for now 🤫
