"...And could you tell us, if you wanted to?" Terrence asks curiously. A slim possibility but maybe worth checking out.

"Yes," Roby says, in answer to one or possibly both questions.

Well, there goes that idea.

Terrence just stares at Roby with big eyes, instead. He's realizing that Roby is not going to help himself. Terrence is reminded of how very much he wants to help Roby. He kind of hopes that Roby's right and that he doesn't need their help after all.

"Why did you do it?" Oscar asks.

"Song of my soul, my voice is dead;
Die thou, unsung, as tears unshed
Shall dry and die in
Lost Carcosa."

His voice is broken.

Why is magic capable of doing this to people.

"What happened to her? Did she walk in at the wrong moment? Did you lose control of the byakhee?"

"...Did you ever have control of the byakhee?"

Roby doesn't answer.

Will a different tack work? "Did you have a byakhee whistle?"

"Yes."

"What did you use it for?"

Silence.

"What are the byakhee? What relation do they have to the pillars?"

"They are His heralds."

"They fly to lost Carcosa..."

"Oh."

--Well that just sounds wonderful!

"Why do they kill?"

"When He commands."

Cool! Terrence is filled with anxiety.

"Did they kill the people in Clare Melford? Or was that something else?"

"To see Him is to die in ecstasy."

"Sometimes."

"But is it also to die by having your entrails ripped out," he mutters.

Nothing about this is encouraging and she's writing it all down.

Terrence is committing all of this experience to memory.

Hey, at least 'lots of people seem to die around Roby, and he thinks a made up entity is ordering these deaths' is at least something that will sound coherent to Dr Aarons!
