"I thought you might be able to draw a map of Dis from memory," she explains. She isn't sure how common knowledge of Dis is, but thought it reasonable that someone who would planeshift to Dis might be familiar with its layout. She knows where Abrogail was and what she did for the brief moment in Hell. She doesn't think of drawing a map as being a particularly rare skill. "Which would then show you that it has been demolished." She believes this, and doesn't find it particularly remarkable that Dis could be destroyed. She thinks of approximately everything as being possible to destroy.
"But yes, it makes perfect sense to start with an outline," she agrees. She is slightly embarrassed that she didn't anticipate Abrogail's request. Part of her self-image is built around being able to competently provide people with things.
"Approximately a day ago on this plane (time didn't match with Golarion exactly, although they are now synced), a member of my self-tree encountered an interplanar bar," she continues. She knows this is hard to believe, and thinks of this part of the story as being the most unusual. Despite that, she has confirmed the existence of the interplanar bar herself, and believes that the events she is recounting are accurate. "Prior to that, my world had no contact with other planes. The bar occasionally attaches itself to doorways in different planes. There, she met a fighter from the Worldwound, who had encountered the bar shortly before."
She is eliding significant information about the identity of the fighter and the member of her self-tree's interactions with him.
"The fighter explained circumstances on Golarion, particularly the existence of Hell. We objected," she continues. She thinks of herself as a core part of the decision-making apparatus of her self-tree. "With the fighter's assistance, we made contact with the Chaotic Good gods, and through them the other Good gods." This is true, but eliding significant effort, worry, and uncertainty.
"With the gods' assistance, we were able to figure out how to use our local technology to cast many thousands of Wishes per second." This is also true, although she thinks of the gods assistance in obtaining these Wishes as being not very much compared to her (personal?) contribution. She is also understating what they accomplished. She wants to avoid scaring Abrogail, and feels as though if Abrogail understood her capabilities she would be scared.
"We used those Wishes -- and other related techniques -- to evacuate everyone from Hell, relocating them to the Good-aligned planes." This is true, although the Wishes were not used to move the majority of souls.
"As mentioned in the letter, this caused Asmodeus to release Rovagug, so we had to move the majority of the population to rescue environments here, in my world. You weren't moved because the gods informed us that people wearing artifacts would be able to make their own escapes, and might be too dangerous to have near the rest of the evacuees." She thinks this generic estimate was probably right on average, but doesn't think of Abrogail as one of the dangerous artifact wearers.
"I was monitoring the war in Avernus when you plane shifted in, and diverted you here after establishing that you would likely do better here than in the holding cells in Heaven," she concludes. She definitely has memories of doing this herself, but several weeks ago, not a minute ago. "Would you like a Wish as a demonstration?" she asks. The offer is genuine. She expects to be able to furnish a Wish instantly at negligible cost, and doesn't expect anything Abrogail can wish for to be a significant problem, although she's prepared to re-evaluate that if Abrogail surprises her with a new Wish wording.
Abrogail might notice, at this point, that the embroidery on Hazel's dress is shifting very slowly in an intricate pattern.
