"Hey, don't rush me. I want to tell you all about the use of Hypercubes and how they're used by Time Lords to interact with each oth-" the Doctor began to explain before his eyes suddenly widened and he stared at the glowing cube in his hands with a new found interest. "Now that is interesting."<br/><br/>He pressed the corners of the box with his fingers and at once an unearthly voice rang out from it. The Doctor winced as it spoke with gargled words that made his ears hurt, but eventually the distorted voice cleared and a different voice took its place.<br/><br/><em>"Hello? Hello, can anyone hear me?"</em>A smooth deep voice asked.<em>"Wait...that's not how these things work. I guess I just have to hope that you can hear me."</em><br/><br/>The Doctor walked over to Robin as he watched the cube pulse and glow. On the side of it was a black marking of a serpent biting its own tail, but the Doctor didn't seem at all interested in explaining what it was.<br/><br/><em>"If you are listening to this, then you must be the Doctor. And knowing how you work I advise you to remain silent whilst the message plays. We cannot afford any slip up,"</em>the voice spoke sternly, causing the Doctor to glare a little at the box, as if offended by its slight on him.<em>"What you are staring at is a gateway between dimensions. In three days this gateway will open wider due to the walls of the universe breaking down. I cannot tell you why this is happening, because I do not know."</em><br/><br/>"Well, that's helpful!" The Doctor hugged before flinching as the cube shushed him.<br/><br/><em>"Don't get snippy with me now. The situation is dire and you need to take it seriously. In three days you will return to this spot. It is important that you wait exactly three days, don't use the TARDIS to skip forwards, from what I have seen, you won't have time,"</em>The voice said solemnly.<em>"My universe is being threatened by something terrible and I won't be able to protect it. I'm going to be out of action for quite a while. I need you to step forward and help defend it for me. I know I ask much, but you're the only one who can do it."</em><br/><br/><em>"Well, I tell a lie, there are an infinite amount of others that could do it, you're just the one who was lucky enough to catch the Hypercube, but the point still stands,"</em>the voice said patronizingly. For a moment the Doctor almost hurled it back out the TARDIS, the only thing that stopped him was the sincerity of what came next.<em>"Three days Doctor. Don't be a fool and let me down."</em><br/><br/>The cube stopped glowing and for a moment the Doctor was quiet as he examined it in his hand. Then eventually, he huffed again and threw the cube over his shoulder before walking up to the controls of the TARDIS once more.<br/><br/>"Miserable sod," the Doctor muttered whilst setting the TARDIS for its next journey. "No matter what version I encounter they're always dead flippin grumpy."
