10 Video Game Fates Worse Than Death (Commenter's Edition)
4. Imprisoned Within The Earth - Baldur's Gate
The Baldur's Gate franchise touts the Imprisonment spell, which will confine the affected to a most horrifying fate indeed.
The spell immediately transports the victim to a spherical prison far below the Earth, and the only way to undo this is to cast the opposite spell, Freedom. There's literally no other way to combat Imprisonment.
Because the victim is left in suspended animation, they're also unable to die of natural causes, meaning they're basically trapped within the planet until the Earth is consumed by the Sun in, oh, only another four billion years or so.
It goes without saying that even those with a firm mental constitution would soon find their mind going to jelly when left to their own devices for what may as well be eternity.
