What would happen if a wizard cast imprisonment in an extra-dimensional space?
Say inside a mage's magnificient mansion or similar.
When you cast imprisonment and touch a creature, it is entombed in a state of suspended animation (see the temporal stasis spell) in a small sphere far beneath the surface of the ground. The subject remains there unless a freedom spell is cast at the locale where the imprisonment took place. Magical search by a crystal ball, a locate object spell, or some other similar divination does not reveal the fact that a creature is imprisoned, but discern location does. A wish or miracle spell will not free the recipient, but will reveal where it is entombed. If you know the target's name and some facts about its life, the target takes a -4 penalty on its save.
Will the imprisonment work or will it fail since there is no ground beneath an extra dimensional space?
I guess I'd go with:
If you ever try to cast a spell in conditions where the characteristics of the spell cannot be made to conform, the casting fails and the spell is wasted.
With no ground in which to imprison, the characteristics cannot be made to conform.

That was the part I was worried about too, but then it is not clear which planes imprisonment actually works on as far as I can see.
Material plane: Yes
Shadow plane: ?
Positive/negative energy plane: ?
Plane of air: No
Plane of earth: Yes?
Plane of fire: Yes?
Plane of water: No?
Etheral plane: ?
Astral plane: No
Abbadon: ?
Abyss: ?
Hell: ?
I don't know - I'd be tempted to make things simple by arguing that "ground" as listed in the spell only exists in the material plane.
I would rule that as long as there is something akin to ground beneath the target of the spell then the spell works like normal. In a temporary extra dimensional space I would say the spell works but only as long as the extra dimensional space lasts. When the extra dimensional space goes away the Imprisonment spell ends. The subject could either be deposited on the nearest applicable plane.
