You look up at the structure again. Except for a few lighted windows, it seems very dark and uninviting. A great boom of thunder claps overhead followed by a crack of purple lighting illuminating the dark, thunderhead-filled sky. The rain is falling very hard now, smacked into you by the strong wind. Looking desperately for anything that might give you a reason not to enter the caste. You step out of the overhang and walk a few yards to the edge of a cliff and survey the surroundings. You grab a nearby rock to make sure you aren't blown off in the high winds.
No greenery or civilization of any kind can be seen. It's just mountains, spires, and jagged cliffs of dark rock as far as the eye can see, looking very menacing framed by the thunderous night sky. The noise here is defeating ,with the constant thunder claps, lighting cracks, wind gusts, and rain pelting the ground hard. You've been out in the rain for only a minute or so, but you're already soaked to the bone. Looking back at the castle, too tired and hungry to even consider trying to fly out of here (besides, there's a storm), you give in and run across the flat expanse towards the large oak front doors of the castle. Luckily, there is an overhang over the door, so you are dry for now.
You pull open one and glance inside. You are surprised to see a grand entrance hall, at least three stories high. At the far end of the room, a great staircase goes straight up to a landing before breaking off to two staircase heading left and right. There is also a large stained glass window with a witch and warlock hunched over a bubbling pot on it covering the area above the landing. A moth-eaten red carpet leads from the front door to the staircase. There are wooden tables and chairs all over the room, but all of them are dusty and splintering, looking like they have not been used in ages. On the right wall, on top of a slight platform are four thrones, two large ones in the middle and two smaller ones on either side. These are dusty and weather-worn as well.
Strangely enough, all the torches in here have been lit and are flickering all with full flames, which tells you that they were lit very recently. You look back behind you, having to duck to see under your huge wings, and see the storm raging and the unfriendly looking mountains. Giving in, you go to step through the door, but your massive wings hit the doors. The force of the impact cause your wings to fold up and hang folded on your back like a bat's. Well, that's helpful. You step inside and pull the door closed behind you, causing a loud sound to echo through the massive hall before dying away. You've never felt so alone in your life.
You walk along the moth-eaten carpet and survey the rest of the room. There are many doors set along the walls, some of them open, some of them closed. All of the open ones are dark holes which you cannot see into. You are surprised to see light jutting out from under the doorframe of a few of the closed ones.
You decide to try and open your wings at will. Concentrating heavily, you arch your back and your wings flourish from it with a loud sound like rustling fabric. They extend out to their full size quickly. Concentrating again, you try to move the wings with your mind and are relieved to see your wings folding back (albeit slowly). They resume their position folded up on your back. You do this a few more times to get used to it. Soon, you accomplish it with almost no effort at all.
Glad to able to control your new appendages, you look for a place to bunker down for the night. You're about to embark on a search for a bed (even though it isn't likely in this dilapidated castle) when you hear a loud noise. You look rapidly around the room for the source of the sound.
