Cain began by stitching the edges of the vortex back together, which seemed to stabilize the effect somewhat but also diminished its presence. The remaining portion of this one was actually recognizable as a portion of traveling magic, much like Cain's [Recall] spell, so that is what he used to fill in the blanks, setting the destination for just beside where he was standing, should anything be able to escape once he was finished.
Getting everything to line up wasn't easy, but by the next morning, Cain had a fully woven spell created on the ruins of the vortex. All he had left to do was add mana and they should be able to see if all that hard work was going to pay off.
