Open.
There was no costume that Ichabod intended to wear. With what little he knew of this place and the people therein, he assumed his uniform would have been costume enough. He did not wear it though; it seemed disrespectful to it, and that was something he did not take lightly.
Besides, celebrations were Katrina's forte, yet he was not sure that she would care to come this night, despite the lighthearted mood. It was unusual in this room to say the least; nothing like he had ever known. Probably nothing he would know again, should they ever return home.
He had stopped in to look around, to see if she was here before he returned to the room; far too much time had been spent in the library looking at more than a few books that fanned his curiosity. The time had been forgotten until he heard distant sounds, the celebration of this night was at hand. Terrible things usually happened on this night, and the decor reminded him of... things. At least the Horseman wasn't here, although he pressed his lips together as he shoved the thought to the back of his mind. Instead he stepped in, planning for a brief visit if Katrina was not here before too long.
