Timeless Sleep

This spell sends the target of the spell into a timeless, dreamless sleep. Once the spell has been cast the creature stops aging, the creature can make no saving throws of any kind or any ability checks, the creature cannot perceive any changes to the outside world, the creature cannot take any damage while the spell is in effect. To an outside observer, everything inside the container is completely frozen. This spell can be cast on any medium creature, willing or unwilling. To cast the spell the water filled container must be marked with the appropriate runes and the proper incantations said over it, once this is done, the creature is placed in the container and the container is sealed. As soon as the lid is sealed the spell is complete. The spell will endure indefinitely until the seal is broken or until a set amount of time has passed. Once the spell is broken, the target of the spell is restored to the exact condition they entered the container, unaware of the passage of time since the container sealed entirely.
