"So, you were minding your own business when your space station started ceasing to exist..."

The players who survived Deleted are all in for Who. I wasn't around to fish for new people properly, but five's a decent number. Time Lord, WWII fighter pilot, modern pensioner outreach volunteer, 51st Century technician and Iron Age witch. Got chargen done in about an hour and a half, started by dropping the pilot's plane on the modern community centre, sent the TARDIS in after evacuating the unravelling space station, and then chased the signal to a Roman encampment having a rather early Industrial Revolution, picking up the witch on the way. So there you go. AP may follow.
