While the others begin to follow cautiously to the next floor, Matilda leads the way to the top of the stairs and what appears to be the top floor. Another set of ornate iron double doors. Its surface is covered with a complex array of cogs, latches, and tumblers. The round doorknob is engraved with the image of a nightingale.

"Hmm, interesting," Titaani murmurs, and tries the handle of the doors to see if they're locked.

Matilda watches nervously unsure of what all the clockwork stuff means....

It's locked. Very locked. Multiple locks, by the look of it.

"Will we have to use the chime multiple times?" Titaani asks sadly. 

Ben:

”If we want to see what is inside, yes.  This does feel like an important room, though—maybe the private library itself,” remarks Ben, trying to remember the instructions they received for that room’s location.

"Well, I'll try just doing it once first, then we can always do it again as many times as we need to," Titaani offers, and uses the chime.

Brrooooonnnnnnnngggggg. The chime issues a smooth, clear, reverberating tone that vibrates your entire body. *click* A lock unlocks. (Chime use 6/10 expended.) 

...But the door does not open. Upon closer examination, it appears that this door has eight locks. Seven are still locked.

You also notice, upon examining the doorknob, that there is an inscription around its base. It reads, “Speak My Name.”

" Zybilna? Is that right?", Matilda queries.

"Locked door," Titaani blurts out stupidly, then laughs as Matilda speaks. "Oh, that makes more sense!"

Ben:

”Too many locks for us without knowing the queen’s truename,” says Ben, “and our clues to that lie in her private library, if what we have been told is correct.  Let’s continue to explore and come back to this room once we have the answer.”

”Unless this is a simple riddle,” he adds, shrugging, and speaks the phrase ‘my name’ in Sylvan.

Pud sits back and waits for everyone else to give it a try. If no nothing else works, he leans in close to the door knob and says "...Iggwilv."

Matilda: "Zybilna?" – Nothing.
Titaani: "Locked door" – Nothing.
Ben: "my name" (in Sylvan) – Nothing.
Pud: "Iggwilv" – Nothing.

The door remains firmly, multiply locked.

Horatio waits for the others. When they're ready, he follows along. "Great. Reading books in a library..." He mutters. 

Matilda frowns, " Have we heard any other names?"

"Aside from our own? I don't think so," Titaani shrugs. "Ben's right, we should probably turn around and try again later."

"Rats. Maybe we can check out the double doors we passed on the way up?"

Pud lingers behind letting the others move passed him down the stairs. He waits for a bit, leans in close to the lock and whispers "Baba Yaga."

If that doesn't work, he'll run down the stairs and join the others.

Pud: "Baba Yaga." – Nothing.

The party retreats downstairs to the next landing.

A set of double doors lead off the landing, topped with the familiar marble cameo of a hart wearing a crown. They are firmly locked.
 

" Wait.......so what the hell is her real name then?  This must be her room."

Ben:

"I suppose we might as well try this door," says Ben, "If we can eventually get back to the hatch hallway and go on that boat, we should be able to get to the queen's private library and maybe learn her true name--assuming that is the password for the door."
