Rumors have it that if you were able to split time and space to access the end of a rainbow you would find a great wooden door. If from there you could jump into the next dimension you would find a shimmering gateway that can't quite be explained in a way that your mind can comprehend, but you're suddenly able to move between time. From there you come to another gateway that you somewhat drift/fall/dissolve through into the next dimension where, oh how do I put this..... you can simultaneously see other possible realities and their timelines that you can move across from. And it is here, it is rumored, that this coral came from.
