Could you post to Journey to Waddenzee before you go? Fleur has been waiting for a response for a while...
As discussed at length, this has the potential to be disruptive, and lessen even more the need for magical items.
For what it's worth, IMO:
Fire with ring/circles are, as far as I can tell, OK. The fire is inside the circle, it doesn't leave it
Light sources have been discussed at length, and I find the argument that the light can't leave the circle pervasive. So you'd have magical light inside a circle, but it wouldn't light beyond, anymore that a T: Room InIm spell allows you to see through the room's windows.
Holding concentration runs into the same problem as light IMO.
So I had this for Arachné, which, as far as I can tell, is within the bounds of the system and lessens the worst aspect of these.
For exemple, she has Carved Assassins posted in the covenant, maintained by such circles. The limitations outlined here ensure that, instead of, say, having a small ring hidden somewhere with all her Assassins wandering the grounds (Cheeeeeeeeeeese), they are limited to the confines of inscribed circles, which is one of the many reasons for the Eternal Guardianship project, and, IMO, better looking and cooler.
Have a nice vacation! 
I should be on a leave on either the third or the fourth quart of august.
That's okay, I can't stand the Lord of the Rings trilogy, either, and I've read all three at least twice. (Dry and boring...proof that he was a philologist first and a writer a distant second.) I did enjoy The Hobbit, though.
Ok, from that information, iesmith.net/tools/solarcalc.html gives that the sun's altitude will be around 32.0° at 9am (local time - timezones of course don't exist yet), and it will be on a bearing 121° clockwise from North. From there the trig is simple. Assuming Guiverna wishes to see the halo, then assume that her viewpoint (that is, her eyes) are 5 feet off the ground. Then we have a right-angled triangle with one point at her eyes; a horizontal edge of unknown length running from there to 5ft up the obelisk; a vertical edge of 65 ft to the top of the obelisk; and we know that the angle at G's eyes is 32 degrees. We want the unknown horizontal length - call it x
Then we know that 65/x = tan(32°) = 0.625; hence x = 65/0.625 = 104.
So Guiverna should put her obelisk 104 feet away from her viewing point, at a bearing of 121.
(I can make a picture if needed).
Well, except from the fact that you used the words "trig" and "simple" in the same sentence 
, I think I got it. At least I know where to put it if I ever get around to making a map of her Quarter.
The bearing of 121, that puts it 31° south of east, right? (Due east is 90°, due south is 180°, I think?)
I just want to be sure I have the sequence straight in my head before I have Epona and/or Guiverna do or say anything.
Fleur left for Durenmar, taking only her shield grog (Epona) with her, and will come back for anyone who wants to help her deal with Vulcanus, right?
If necessary, yes.
It al sounds good to me. However, until just now, I was unaware that Fleur took anyone with her, nor did I realize Epona was assigned as her shield grog. AFAIK, Epona was a private employee of Vibria. I suppose Fleur has the option to hire her. I just figured she was waiting around for her boss to return.
However, she has no status in the Andorran Guard as of yet. If Roberto's defense plan (from 1236) is approved, the offer to become a warrent officer is on the tabe. But if so, that is a responsability much more important than mere shield grog.
Just putting it out there...
Just to add, it should be a short trip. Portal to Harco, then portal to Durenmar. Wadanzee has no portal.
However, Carmen can teleport or fly straight to Wadanzee. She will travel via flying carpet if anyone wants to go with. She plans on heading out directly there as soon as Fleur departs in an attempt to head her off and warn Vulcanus. Though the part about warning him, she keeps that to herself for now.
Fleur took in both Epona (as her shield grog) and Lucia (as her maid) when Vibria left.
Can she serve as Huntmistress and Archer, and detach as a shield grog as required? I don't think Fleur leaves the covenant that often (once this cycle...twice if you count "sell apprentice" on the planner for Summer of 1241).
I am not disputing it. Just saying I was unaware of any official status. In that light, certain other things make sense.
As for shield grogs...
Anyone can personally hire anyone they want. If one desires a shield grog from the Andorran Guard, inform the officer in charge of that and he will assign someone. If you desire someone specific, that can be accomodated.
Having said that, Epona is not part of the guard. If allowed, Roberto would make her a warrent officer, and as an officer the duties of the enlisted are below her status and her skills are too valueable (supposedly) for menial tasks such as being a body guard.
However (I use that word a lot), Epona can do what she wants with her free time. And a Warrent Officer, as a specialist, can take up or set aside their warrent as they please I suppose.
Roberto would not want to recruit her in another capacity. She is not soldier material. Roberto's qualms about female infantry aside, she wouldn't fit into a trained combat team.
So it is either Free Agent or Hunt Master. She cannot have both.
And mind you, I was just trying to find an official capacity out of what I thought was a loose character. Roberto's plan does not involve recruting new people. It mainly involves working with the material on hand already. If he had his way (which he can't), even our scribes would have military rank and martial training.
In my opinion, Harry Potter is better than LotR. I has more character depth and originality. But it is just so campy it makes me wince. That whole flying broom polo game thing....uggggh!!
The Goblet of Fire was a cool movie though. That is the only one I saw all the way through. Other before it in snippets. Never read the books.
As for LotR, I tries reading the first a few times but I can never make it past the thousands of pages of wandering through green hills. I fall asleep within a page. The barrow wight was cool, but Tom Bombadillo is stupid and I just gave up. The movies were okay, over long and also campy, but okay.
Maybe it is the British novel style. Hate Tess of the Dubervils ten times as much. Instant sleep. Moorcock is okay for short stories, and only about Elric. His other work is crap. I heard Hawkmoon was good, never tried it yet.
Maybe I am just hooked on the American literary style. Robert Howard, Stan Lee, Robert Hienlien, Neil Strauss, Ernest Hemmingway. Stuff like that.
I'm ashamedly a reader of all the writers you've mentioned and far more schlock and artistry than that too- Reading is escapism. I'm slowly reading Cormac McCarthy at present and enjoying Larry Niven
The only reasons LOTR doesn't seem original is because it has been copied so often. It was the original.
Mark, you really need to read The Dresden Files. And, bonus points you get to see the main character tromping around and destroying stuff in your home town.
The Spider agrees with him. This is in part how they did it in insidiae.
Totally!!!
Very much seconded.
Dresden Files aren't my favorite series, but they're cool, easy fun, and better on that aspect than some of my favorites. I enjoyed them thoroughly.
Also, it's one of the few series in which there's some aging, which is cool.
I have heard positive things about Dresden. I will check it out.
And I strongly dispute the idea that LotR was the original. The works of Robert E Howard (Conan, Kull, Solomon Kane, Red Sonja) predate Tolkien by 15 to 20 years. Edger Rice. There are tidbits of earlier fantasy, but Howard pretty much invented the "sword & sorcery" genre and popularized it long before Tolkien. And all Tolkien did is take the script from WWII and change the names.
And that Blue Man group...
Total rip-off of the Smurfs!
Oh, I also enjoy all of the Vlad Taltos novels from Steven Brust. There's another series of books done in the same world, but told in a different style of voice that I can't actually tolerate, and one of the Brust novels (Tiassa) uses that fictional narrator in part of the book, so I have to flag that one.
Epona would be honored and delighted to become Huntmistress and Archer (her two strong suits), as long as she doesn't have to do any actual teaching herself. She's a rubbish teacher – just ask Lucia (who she's been taking hunting and camping the last couple of years when they have time).
And her being a Warrant Officer would explain why she's not in the War in the Roses thread. I was going to explain it as "recovering from a training injury", but I like this explanation better.
