The foyer is just as you remember it when you saw it not long ago. A testament to the wasteful lifestyle of the Canterlot elite and a commentary on the impermanence of wealth.
Gold paint flecks off the gilded banisters like dandruff, leaving bare unvarnished wood behind. The once beautiful red carpet is now a reddish brown, like old dried blood, ripped and torn to shreds by the elements, wild animals, and unruly teens. A chandelier lies cast to one side, a sad memory made of rusted metal and shattered crystal.
The only light comes from the rows of jack-o-lanterns that line the walls and what traces of the silver moon can seep in through the holes in the walls. You shiver as a chilly October breeze slips in along with the moonlight.
"Hold," declares an all-too-familiar voice. "Who is it that doth treadth before mineself?"
Your gaze rises to the balcony, where you're greeted by the sight of Trixie, but not as you last saw her. Gone is her cheap costume and in its place is a set or armor. Black as night with midnight blue accents. It's armor you've only seen once before, but a set you'll never forget.
"You know that's totally offensive, right?" You only hope that Princess Luna never catches wind of it, if not for Trixie's sake then any nearby uninsured property by proxy. "Where did you even get Nightmare Moon's armor?"
"Our most glorious and royal self madeth it, of course," she preens, completely unapologetic and fearless about dredging up a dark and painful part of a ruling princess' history. "Twas molded and shapedeth through arcane means out of the very fabric of... hey! Where are you— I mean where art thou going?"
Anywhere but here. You may be willing to go through a lot of stuff for the sake of a haunted house, but potentially upsetting Princess Luna? That's a punch above your weight class. Seeing a fully grown princess tear up is almost as bad as watching Scootaloo or one of her friends cry. You'll have no part in it.
There doesn't seem to be anything to interact with in this room, but there are three hallways that branch off that head LEFT, FORWARD, and RIGHT.
