Out of Time's Grip

As discussed in the first chapter, time does not actually pass on the Astral Plane, but it catches up with an individual once she leaves. This spell was created by the githyanki to enable them to leave the Astral for short periods without feeling the effects of the time that they've cheated. For the duration of the spell, the recipient can operate freely on any plane without worrying about retroactive aging for the time she spent on the Astral. If she stays off the Astral longer than the duration, time immediately catches up with her and she instantly ages all the time that she spent on the Astral, as normal. A successful casting of dispel magic will cause the spell's effect to stop.
