"Theorizing again, but I'll allow it for the sake of your instincts having been on the right track before... A bullet is a type of bolt in simple terms, and it was enough to kill the queen in one go. As to whom did it."

"It was her own sons and daughters."

"One last question. The answer to this one is rather poetic, if you ask me."

"Why did the titans seal away magic?"

"Her own sons and daughters...  So, elvenkind, or literally her direct children.  But that still isn't enough to work out what they were attempting to shoot, that they could hit her by mistake.  As for the titans sealing away magic...  This is another I cannot even pose a theory for.  Why did they?"

"..."

"..."

"..."

"Because this world deserved it."

"You follow the path of the scholar. Take your reward, and I shall remain here should you need me."

Another disk falls out of the mask's mouth, alongside a brooch.

Sylvia soon comes flying along to helpfully translate the text on this disk seems to be "Eyes". It joins the other three collected so far, namely "Blood", "flesh" and "breath".

Rick asks Lore,

"Lore, why is Lore such a "#%¤?"

He doesn't wait for an answer as he stomps back to the central room with the doors.

"Rick wants to hit something. Which room had the Floating Armor? Send Bandit upfront, Rick and Rick's Friends and Rick's Associates will fix Floating Armor."

"I don't know that language but I feel like I would be deeply insulted if I did..." 

"I believe my associate is rather upset that we were never expected to be able to answer every question.  Or even most of them.  I do have another question for you, though.  There is an occurrence among some races, such as elves and centaurs, where our body gradually becomes petrified.  Does it have something to do with magic being sealed?"

Rick presumably almost forcefully drags Cladmir toward the "reality" door, which, opening it again... Yes, it does seem like the suit of armor they fought yesterday is gone, and everything looks as it were before. Three longer segments, segregated by narrowings of the wall, until eventually reaching the far room that seems to hold another one of those disks...

Khond meanwhile, continues conversing with the lore mask, asking a question about whether or not being turned in stone is related to magic being sealed.

"...In a way. Without magic in the air, your body cannot fight off the curse."

"I already know you are going to ask further on that topic, but I am afraid I do not possess that much more knowledge on this subject, and it's one of the topics I cannot divulge more about regardless."

"But if you choose to finish all my brothers and explore deeper, you might discover more."

Luckily Sylvera is not around at the moment. She'd probably have way too many questions having heard this.

"A curse...  That just creates more questions...  Well, if I think of any other subjects to ask you about, I will return here."

Khond collects the disc and brooch before heading after Rick, "Don't forget that hall is filled with traps, Rick.  One wrong step and you'll have a dozen bolts through you."

"Rick solved that."

He nudges Cladmir forward,

"Bandit heard Friend Khond? Bandit best be careful!"
