Duma smiled as The Doctor entered, blowing out the piece of paper he had been using to light the candles. He hurried over to the Time Lord, offering to shake his hand rather than wave in greeting. He then gestured, offering a place to sit where the candles wouldn't get too close to anything flammable on his guest.

Sighing slightly, Duma picked up his pen and paper, and wrote the message It's not much of a place. It is very dark. But it's where I am, for now. Welcome, it is nice to physically meet you
He handed the piece of paper to The Doctor, looking slightly sheepish and hoping that he understood.
