"I believe our business is concluded. For security reasons, I can't let you leave just yet. Do you have anything you'll be missing if you don't return to Almas today?"

A quick smile, and she shakes her head. "I do not. If you wish to meet my possible familiar—" 

Morgethai cares about her own familiar, this conversation would be better if she demonstrated her own concern, it needs an apparent gender to be clear she thinks of it as a person, what does it present as? Drow sign has slightly gendered positionings, mostly finger width but it does matter in a few cases, she thinks back— 

Tencednil looks up for a moment, and nods slightly before continuing. Thinking of something, making a quick correction to what she was about to say. "—she should appear in the morning. Or she could be locked to one plane or something like that, I wouldn't know." And that's all she needs to say. She shifts her stance slightly, a bit open but mostly pointing her attention at Morgethai instead of herself. She's listening, but if you want to press further there's more detail she could go in to, it's just not necessary here.

"I would like to meet your possible familiar. If you want, I can turn you to stone for the rest of the day. Otherwise you will be waiting here for... sixteen hours."

"Sixteen hours is fine. My magic just changed, I need to practice it anyway." Her ears twitch. Remember, half-elf. She may not be an elf in full, but some patience when she needs to understand something in depth isn't beyond her. Sixteen hours is a while but there will keep being things to explore.

"Very well." Felandrial sits down at a different desk and starts working on some sort of magic item.

Gallipsiwhoop flies away into the forest beyond the glade.

Hours pass in relative quiet.

Her new ability with magic doesn't actually change what she can cast, but she has much more of a grasp for what's going on, and how to power it. She starts by setting up a Prestidigitation and watching how it works now with a Detect Magic, spotting the little snags and errors in the spell which are smoothed out and now snap cleanly at her direction. That definitely would allow the spell to force its way through more resistance. Once she's happy with that, she goes to find a shadow and starts practicing her shadow cantrip, both with and without the metamagic. It integrates smoothly with the spell, so as a whole it's still a cantrip, which means she can get a much better grasp of exactly what she's doing than with anything she can only cast a single-digit number of times a day. It's a different feeling from Acid Splash's replication of brimstone. Maybe they really are fundamentally different tasks?

If Gallipsiwhoop or Morgethai don't look busy, she'll try to find a chance to ask. If they are busy, she can keep experimenting for hours. The subtle differences in the structure under Detect Magic are endlessly intriguing, as is investigating the location they're in as a whole. It's not the same as extradimensional spaces, it's definitely doing something different, and whatever it is is far more complicated than the simple beautiful clarity of the Wish. It doesn't look any less unique and complex, though.

Gallipsiwhoop is available to answer questions about magic. "The method sorcerers use to eschew minor material components is not metamagic."

"Oh! It feels very similar from the inside to me, it's just replicating the effect with an internal source instead of an external one. Do all sorcerers need different sorts of components? I know song-sorcerers need to sing." All of her attention focused on Gallipsiwhoop, listening for any tidbits of how this all actually works from a source who knows far more than she does and is probably the best-studied public figure on Golarion on this subject. (With the possible exception of Nefreti Clepati, who is too insane to actually be a reliable source.)

"Song-sorcerers can't ignore minor material components like regular sorcerers. At least not by default. It is possible to develop the skill as a wizard and I assume this is also true for other spellcasters but I've never checked."

"Interesting! And it's not a metamagic like Silent or Still is, just a thing that can be learned. I wonder what the metamagic pull is, then, it integrates very smoothly with my shadow cantrip?" Head tilted, eyes away, considering the possibilities that would be misleading, so she can't. Instead, she shifts slightly, her eyebrows rising, and it's clear that this is as much a question for Gallipsiwhoop as it is a subject she's going to think about herself.

"The shadow trick you use to cast second circle spells is some sort of metamagic, but I'm unfamiliar with this particular kind. Wizards use specific techniques to learn metamagic. If you don't know its source, I expect it comes from your sorcery in some way."

Nod. "That makes sense."

And now she will go look at the magic built into this place, instead of spending more time on that. This Geas is for the best, and the results were definitely worth the cost, but it's kind of embarrassing to have her communication strategies so reduced.

Magic flows through every inch of this place. After fifteen minutes of concentrating on detect magic, Tencednil isolates a few different auras. There's a strong conjuration aura, two moderate abjuration auras, and two moderate universal auras. She can't identify any of the spells in particular.

Moderate universal... that must be a Permanency, right? Well, two of them. Are there any other universal spells in the right circle range? The conjuration is probably the thing creating the space, which is interesting, because the mirror extradimensional space was transmutation. She has no idea what the abjuration auras are, but at least one of them must be the other permanent effect. (She has no idea whether the conjuration needs a Permanency, but at least one of them must be on an abjuration.)

...right, and she had to say a password to come in, which was probably a Forbiddance. That would be one of the abjurations, then, so the conjuration does need a Permanency to stick around, and whatever the other abjuration is is probably to block scrying somehow. Or some other sort of protection which needs a Permanency, there are many things she can imagine an archmage wanting in their personal non-spatial area.

The interweaving of the spells and the way the Permanency connects to the entire amalgam is fascinating. She spends quite a while just looking at the magic, watching it go by, and seeing a little but more of what it is to be an archmage.

Gallipsiwhoop joins Felandriel at the workshop as they work on some other item. Eventually she retires within a house in the woods.

Hours pass.

Shortly before Felandriel went to her house, Tencednil asked where she could sleep. She'll be out for the standard eight hours.

Felandriel will let the girl sleep. Goodness knows she probably needs it after all that.

Her sleep is boring and entirely standard, though she is a little restless as a result of having Teleported a thousand miles in the past few days, with the resulting confusion in her schedule. Fortunately the demiplane allows her to sleep without as much light creeping through cracks as there was in the inn room from... was that really yesterday?

Eventually, she wakes up.

"The security concern has passed. Gallipsiwhoop will take you back to Almas soon. If your potential familiar is here, I'd like to meet them."

"Sounds good." She smiles and goes behind a tree that would be deceptive, she simply flicks her fingers, flexes her shadow in the place that doesn't really exist, and the blob pops out of it and bounces.

Tencednil winces slightly. "And is now the right time to ask you to remove the Geas?"

"Of course." Felandriel dismisses the lesser geas.

Oh wow. Her body language suddenly half-vanishes, as she is no longer being dragged around like a puppet to perfectly convey her true feelings. She shifts a little, feeling out what it's like to move with this understanding of what it means. A twist like that to convey attention, a minor re-angling to be impatient, a quick sway of her eyes to be merely feigning it... She'll be a few moments getting her sense of herself back together.

The shadow blob ignores this entirely and buzzes happily at Gallipsiwhoop. <Hi!>

Hello, little shadow.
