"You have probably seen mentions of doors over the comms, over the network. Those doors open to a variety of different points in time and space. Not just that, but different universes. There is a chance we could somehow bring a door to the Worlds of Progress, but I am still not entirely sure how..." he paused.
The Doctor hated admitting that he might be unsure about something. He had been trying to figure things out since he arrived on the station. He wasn't sure if he really bought the idea of intent summoning doors. After all he didn't really think magic was an actual thing. Trickery and technology disguised perhaps but that was it.
