The four Doctors looked all around in every direction before looking up to where the gravity lift was streaming up to in the sky, beyond the fake artificial sky. 'Something here is enforcing a blocking signal, your companions were able to contact you both for a while before they were shut out' Nine said as he looked at Ten and Twelve 'your TARDIS's were experiencing flight troubles, so the same block could be preventing them from materialising and landing here if they're trying to get through'. Twelve looked up where the gravity lift was going again 'we need to follow this gravity lift up, it'll lead us to whoever or whatever is behind all this' he said, Ten and Eleven both nodded 'yep' and 'yes' they said.
Nine looked to his future selves before he gestured for them to come forward 'right let's go' he said, Ten, Eleven and Twelve stepped forward onto the floor of the gravity lift with Nine doing the same and seconds later they began to rise up through the cylinder-like stream of energy that was the gravity lift well towards the same receiving port. As they did so the four Doctors took what time they had before they would enter through the receiving port in the sky to take in and admire and appreciate the view of the landscape they had each found themselves in hours ago with its circular lake and island bang smack in the middle of it all almost like a bull's eye and almost entirely green and forested landscape with patches of bare and grassy land about the place surrounding it. Half a minute later they disappeared into the receiving port in the sky…
…some seconds after the four Doctors entered into the port in the sky, hollow and stuttered sounds of the TARDIS engines could be heard in an echoing way as one after another each the four Doctors TARDIS'es briefly materialised in the air miles above the contained land in a troubled way before disappearing again. First the Ninth Doctor's TARDIS with Rose inside then the Tenth Doctor's TARDIS after its past version disappeared again with a slight zap then the Eleventh Doctor's TARDIS then the Twelfth's in the same fashion. Inside each TARDIS each of the four Doctor's companions were shaken about tumbling and holding onto the console as much as they could for all it was worth as the TARDIS they each occupied tried, struggled and failed to land.
Elsewhere…
A cloaked and hooded figure in a robe sat before a big and wide glass window with a view of space beyond it. In front of him were multiple individual projected hologram displays, one of which had a view of the gravity lift that the four incarnations of the Doctor had gone up before disappearing into the port in the sky that had been partially concealed by a perception filter as well as the artificial sky. The hooded figure had been somewhat surprised by how soon the four Doctors had spotted the peculiarity in the patch of artificial sky that the gravity lift had been streaming through, and then through that perceived the port hole through the slight concealment of the perception filter which was a very powerful variant. Never mind, it was only a matter of time before the Doctor and his other selves caught on to things the hooded man thought as he watched another display of the four Doctors going up the gravity lift shaft together and getting closer to finding him 'not long now Doctors, soon…' the hooded man said.
