Cosmic blade

The cosmic blade, now stabilized by the Valco Stone

Jack realized that the sword was made of condensed black holes. Upon later inspection, he noted that it could slice through any object, and easily transport objects other than Jack into other dimensions and create new dimensions for any specific purpose. However, Jack also noted that the weapon was highly unstable. It had an indent in the handle that was shaped much like the Valco Stone. Knowing the Valco stone from the current dimension should not be used lest it fall into evil hands, Jack traveled to another, uncolonized dimension and retrieved the Valco Stone from that dimension to stabilize the sword. After returning to his original dimension, he decided to call the now stabilized sword the Cosmic Blade.
