That's a really funny smell.
It's almost human but not quite, and it's nowhere near hybrid or wolf. A new species, or an unusual witch? He goes check it out.
"Never seen an unbreakable object before?"
"Nope. Not unbreakable by me."
The Master descends the stairwell.
There's a landing with a bookcase and small bed tucked under a window that also leads to nothing.
At the bottom of the stairwell there's a small cozy room that contains a wooden stove and large table.
The front door of the lighthouse opens into a sweets shop. It is almost empty, but all of the baked goods are fresh.
"What is the point of this place?" he wonders aloud, exploring everything faster than the human and (probably) the Time Lord can track him.
"Someone was bored," the Master suggests.
The sweets shop's large front glass window leads to a cabin filled with bunkbeds made with a variety of colorful sheets. The cabin intersects where the lighthouse should be with no obvious difficulty.
The door behind the counter leads to a storage room filled with plywood and construction tools.
"This place is messing with Euclidean geometry like no one's business."
"This has just raised my credence that I'm in a psionic illusion," he comments lightly.
The Master pops a sweet into his mouth.
"No good psion would make anything taste fake," he says, rolling his eyes, but he also pops a sweet into his mouth. "Hmm... Okay it also feels real to biokinesis so I guess either a very good psion or not one at all."
"A psion would have to be a little crazy to make me up."
"Two years in virtuality can do that to a person."
The Master picks up the chair behind the counter and throws it at the front window.
The glass cracks.
Vampire Sadde goes over to the window and lightly taps it, just barely enough to smash it.
The glass shatters.
The cabin beyond looks like it was recently in use. Some of the beds are unmade and there are stuffed animals sitting on pillows and tucked under sheets.
"What even is this place," vampire Sadde wonders, zipping to explore it.
"I don't like the effect of these nothing windows."
"Scared of a little darkness?"
"I can see in the dark! This is freaky!"
"I mean, yeah, kinda?"
"It's just nothing. It can't actually do anything."
