Imprisonment (Reversible)
The power of this spell hurls the victim deep beneath the earth, placing it into a state of suspended animation for eternity, entombed within a cyst of rock. The only way to free an imprisoned creature is with the reverse of the spell, and the caster must know the name of the prisoner together with enough detail to clearly identify him or her. A creature freed from imprisonment appears at the exact spot where the imprisonment took place. When casting the spell’s reverse, if the caster is not specific enough about the imprisoned creature’s identity the spell will normally fail; but there is also a chance it will free the intended creature together with several other imprisoned victims from other places in the ground—some far, some (perhaps) near. Some of these freed victims might be from ancient ages and may have been imprisoned for a very good reason. The chance of freeing unintended recipients is 1 in 10, and their number can vary considerably (d%).
