The right hallway turns into an alcove with a door in it. The left hallway does the same.

Martin goes up to the door at the end of the left hallway and opens it with his assault rifle ready...

Inside, there are some couches and chairs around a fireplace, another door opposite the one Martin opened and one more to his right.

Naru looks through the door in the hallway.

"This castle is so much better than the base in our actual missions. Not metal" she says in an undertone.

Inside is a study, with a desk and armchair.

Naru walks through the doorway and looks for another door.

There is one on her left upon entering the room.

Naru looks through the door on her left.

The side door leads into the throne room. There is nobody in there.

Naru enters the throne room and sits on the chair briefly for kicks, keeping alert for human movement.

Martin opens the door to the right...

Martin's door leads into the throne room, right behind the throne.

Andrew joins the room that Naru is in. "What are you doing?"

"Nothing, lets keep moving"

Seeing Naru and Andrew in the throne room, Martin decides to check the other door up ahead...

It leads into a big bedroom, with decorations that suggest it is the royal bedroom.

Martin walks into the royal bedroom and inspects the whole room more closely, looking for anything out of the ordinary...

Next to the gigantic bed there is a rug that is slightly askew. Everything else in the room is perfectly neat.

Naru investigates the rug.

Andrew points his gun off to the side of where Naru is investigating, ready to fire if needed....

Under the rug there is a metal trapdoor.

Martin slowly opens the trap door with his gun ready...

There are lights below, and a ladder leading down there.

"Alright, lets go", Martin climbs down the ladder...

When he reaches the bottom, a gun is pressed into his back.
"I think you might want to drop your weapon."
