On board the TARDIS, time vortex in a different universe
The Doctor sat on the stairs in the console room, pondering about his recent loss of his friends. They had a good run together. So many defeated threats, so many victories. And most importantly of all, the Doctor thought: dinosaurs on a spaceship! He smiled at that thought. And it had all started with a scary crack in Amelia's wall.
He got up and walked up to the console to set a destination and fly out of the time vortex. The Doctor flipped levers and pressed buttons as he walked around the console configuring everything for the landing. Suddenly the TARDIS started to rumble violently and the engines wheezed and coughed as if they were in pain. The cloister bell rang indicating potentially impending danger. "Woah, come on old girl, no time to grieve about them now! What's going on?! It's just a simple landing, you can do it!" He stumbled over to the monitor to get status readings. The outer shell of the TARDIS was being surrounded by green field of energy and particles. "What the hell is happening?! These readings are off the chart; shields are down! It's as if we are vanishing from the time vortex, but - woah wohw" Another quake pushed him off his feet and he landed on his six a bit roughly. Sparks were going off here and there and the engines changed their pitch to a near screeching. "Ow! But that's not possible! We're not landing, we're not flying in the time vortex anymore, where the hell are we going if not nowhere?! You can't go nowhere, that'd be ridiculous!" he yelled out to himself over the gradually increasing rumbling.
And so the TARDIS got sucked out of the time vortex into a Combine interdimensional portal and was being propelled towards the earth that was currently struggling to rebel against the Combine. "Fear not, great Healer. We have used the Vortessence to procure you, for you are required to assist in time of grave need." a voice in the Doctor's head said. "Who are you?!" the Doctor demanded to know. "We are the Vortigaunt-kind." the voice replied. "Tell you what, next time you'd like my help, can't you just call or knock on the front door instead of snatching my TARDIS with me in it?!" the Doctor coughed out yelling as he pulled himself up on the railing. "The Healer is asked to excuse the great disruption, as it is the only procedure of potential operation. We have broken the veil of time and space that covered your world to bring you to your purpose." the voice answered justifying what was happening. "Farewell for now, great Healer. We are anticipating the fulfilment of the cause yet there is one quest to endure before we are allowed to tread a single road in taking a stand." As it said that, the TARDIS exited the Combine portal in City 17 a few moments after the portal storm. It stopped rumbling and quaking and the engines quickly returned to their normal healthy in-flight pitch while abnormally slowly dematerialising mid-air.
"Hold on… This is a parallel universe!" the Doctor recognised. "Ohhnoo, notagain. And what are we dematerialising for?! Ohnononono. Stop that! The time-space coordinates were set for the future in our universe; don't just recalibrate and translate them for this one! That's what I get for stealing a type 40 TARDIS: the navigation systems are just a nightmare!" The TARDIS started to materialise and land on its own. It was a slower landing than usually, just like the take off had been slower. Once it was completed, the Doctor set the space-time throttle to zero and put the handbrake on. He leaned against the console to catch his breath. "OK, now… Where are we…."
