Box of Safe Storage

You create a magical steel box with a slight glow coming from it.  The Caster chooses a bloodline that will own the magical box until it is destroyed. The box will automatically be linked up with all other magical boxes that is owned by said bloodline but if destroyed only that box will be destroyed. If all boxes are destroyed everything stored in the boxes will go into a ghost-like form and be thrown into The Astrial Sea until a new box is created for the bloodline. To open a Box of Safe Storage you will need a drop of fresh blood (Max 2 hours old) from the bloodline that the Box of Safe Storage consumes. When a Box of Safe Storage is destroyed if will disappear into nothing. To destroy a Box of Safe Storage you would need an insane amount of power or energy (It is up to the DM to determine how much is needed to destroy a Box of Safe Storage)
