Turning 02, and you can go all the way round it
Sithen
A hillock inhabited by fairies
A ring of earth and whitethorn standing in a field, which you can walk all the way round and will not be going into. That is not coyness and it is not an unfinished room. The outside is the part of a fairy fort that anybody has ever actually seen. The inside is the part the stories are careful never to show you, and a page that flung the door open would be making up the one thing the tradition declines to.
What the name is, and whose it is not
Sithen is a real word and it was checked rather than assumed. Scottish Gaelic sìthean — a hillock inhabited by fairies — from sìth, fairy, with the diminutive ending; there is a dictionary behind it rather than a vibe. The Irish is sídhe, in the reformed spelling sí, which is the mound itself, and is where aos sí — the people of the mound — comes from.
This mattered enough to look up. Two novel series are what sent us here, and one of them uses this exact spelling for the fae court, so a room taking the name while claiming to owe those books nothing would be advertising a debt it does not otherwise have. It turns out the word is older than both. It is said here so that nobody has to assume either way.
The ground, which is documented
This half is earthworks and a motorway, and it is kept apart from the folklore below on purpose, because the two are not the same kind of claim and a reader should not have to tell them apart by tone.
-
A fairy fort is a ringfort: lios or rath, a circular earth bank, sometimes a ditch, sometimes stone.
People built them from possibly the late Iron Age into early Christian times, and because the buildings inside were not durable, what is usually left in a field now is a vague circular mark and whatever has grown on it.
-
As of 1991 there were between thirty and forty thousand identifiable fairy forts in the Irish countryside.
The oldest of them possibly date back as early as 600 BCE. This is not a rare or sacred handful of sites. It is an ordinary feature of the landscape, in enormous numbers, that people have declined to plough.
-
Believers in the fairies did not alter them, and even cutting the whitethorn growing on one was reputed to be the death of whoever did it.
The tradition is specific about the thorn. Sceach, whitethorn, hawthorn: the tree of the ring, and the one you leave.
-
In 1999 a whitethorn at Latoon in County Clare stopped a motorway.
The folklorist Eddie Lenihan campaigned to save the tree from being cut down for the M18, calling it a meeting place for the supernatural forces of the region. It was spared in May 1999 and still grows there, on a strip of land between the motorway and a slip road.
A country that routes around a tree
Hold those together for a second, because it is the most interesting thing on this page. Tens of thousands of these rings are sitting in fields, and people decline to plough them. A motorway was rerouted around a single thorn bush. The stated reason is the Good People, and the actual mechanism is that leaving it alone matters to people and the paperwork required for that is a shrug.
We are usually asked for a diagnosis, a letter and a business case before anybody will move a desk. There is no version of this room that does not notice the difference. A whole culture can make an enormous, expensive, permanent accommodation on the strength of this matters and I am not going to justify it to you — and the same culture will ask a Disabled person to evidence a chair.
The rules, which nobody will say out loud
Everything in the left-hand half of these is traditional and says where it comes from. Everything under what it is like is ours, written for this room, and is not claimed to be in the folklore. That split is the whole page: these taboos are a catalogue of consequential rules that nobody will state, where breaking one is punished and no one explains — which is the ordinary weather of neurotypical convention for a great many of us. Nothing here tells you how to behave. There is no advice, because a page about unwritten rules that ended in tips for following them would be a social skills curriculum with thorns on it.
-
01
Do not eat the food.
Accept a meal inside the hill and you may not be able to leave it.
Traditional · A standard motif of the Otherworld visit in Irish and Scottish fairy tradition.
What it is like: The invitation that cannot be declined without a cost. The coffee, the team lunch, the quick chat that is not quick and was never optional. Hospitality is the mechanism, not the kindness: once you have taken it you are inside an arrangement you did not read.
-
02
Do not say thank you.
Thanks implies the debt is settled, which is an insult, and a slight from a mortal is not taken lightly.
Traditional · A widespread motif in fairy etiquette across Irish and Scottish tradition.
What it is like: The rule where the polite thing is the wrong thing. Every autistic person has been punished for a courtesy delivered correctly, in good faith, to somebody who wanted a different courtesy and would not say which. There is no version of this you can work out from first principles, which is the entire complaint.
-
03
Do not give your true name.
A name is a handle. Give the real one and it can be used to call you, bind you, or hold you.
Traditional · The power of the true name is a widespread motif in European fairy tradition.
What it is like: Disclosure. Tell an employer what you are and you have handed over something that can be used to help you or to manage you out, and you will not find out which until afterwards. This is why so many of us are careful about the word, and why nobody should be told they are being paranoid about it.
-
04
Do not accept a gift you cannot return.
An unanswered gift is a debt, and the debt is collected at a time of the giver's choosing.
Traditional · Reciprocity and its dangers are a recurring feature of fairy dealings in the tradition.
What it is like: The favour economy, which is most workplaces. Being helped puts you in a ledger nobody shows you, and the entry is called in later as though it had been agreed. An accommodation offered as a favour rather than as a right is this exactly.
-
05
The bargain is kept to the letter.
What was agreed is delivered precisely, and precisely is not what you meant.
Traditional · The literal-minded bargain is one of the oldest and most consistent motifs in fairy tradition.
What it is like: The accommodation granted on paper. Yes, you may have the software. No, not the training, the licence, the time, or the colleague who stops scheduling meetings in it. Every word of the agreement was honoured. None of it worked, and the record shows you were given what you asked for.
-
06
Do not cut the thorn.
The tree on the ring is left standing, and no one is obliged to explain why.
Traditional · Documented tradition; the whitethorn taboo is specific and is still observed.
What it is like: The accommodation with no justification attached. A whole country routes around a tree because leaving it alone matters to people, and the paperwork for that is a shrug. We are usually asked for a diagnosis, a letter and a business case before anybody will move a desk.
-
07
Time is different inside.
A night of dancing, and everybody you knew is old or gone.
Traditional · The supernatural lapse of time is a central motif of the Otherworld visit.
What it is like: Burnout, and any long illness. You go in for what you are told is a short thing and you come out having missed a stretch of your own life, with everybody else further along the road and nobody quite able to say where it went. Nothing was stolen from you. It is simply gone.
Why the door is not opened
Every other warm underground place on this street is an interior with one small flame in it — a burrow with a lamp, a candlelit tent, panelling, a curtained cave. There is no interior here and there is no flame. Staying outside is what keeps this from being those rooms again with thorns on, and it is also the honest shape of the thing: a fairy fort is an outdoor object, and its whole character is that it is bounded, visible, and not entered.
And it suits the argument. Half the rules above are about hospitality as a trap — the meal, the gift, the debt, the bargain honoured to the letter. A room that then insisted you come inside and accept what is offered would be doing the thing it spent the page describing. You are not obliged to go in anywhere. You can stand on the bank in the cold and look, and leave, and nothing about that is a failure to engage.
If a door is ever opened here it becomes its own world behind this one, the way the Jungle Room grew a den, with its own light and its own rules. It does not become this page with rooms added to it.
What pointed us here, and what is not in this room
Laurell K. Hamilton’s Merry Gentry books and Seanan McGuire’s October Daye books are why this turning exists, and they are named here rather than quietly absorbed. Nothing in this room is drawn from either of them. Not a court, not a character, not a politics, not a cosmology, not a line. Those are invented worlds belonging to living authors, and the difference between being pointed somewhere and helping yourself is the whole of what this site means by attribution.
That refusal is enforced rather than remembered: tools/make-sithen.py will not build this page if a rule’s source names either series or either author. The friendly edit here is a real one and it will arrive — the folklore is thin in exactly the places a novel is rich, so the most useful material lying around is the one thing this room may not pick up.

The documented half was read off Wikipedia’s article on fairy forts and its article on the Latoon fairy bush on 2026-09-22; the name off Aos Sí and Wiktionary, which cites Colin Mark’s Gaelic–English Dictionary (Routledge, 2003). The readings beside the rules are ours.
Job marker — a sprig of thorn on the bank
You have found a job marker. The Adventurer’s Guild is a shopfront on the street, and it posts jobs that send you round these rooms. Take the code below to its board and that job is done. Nothing here is scored, nothing expires, and one is a perfectly good number of jobs to do.
The job: The tree nobody will cut
Before the code: Sithen names one kind of tree that is left standing on a fairy fort, and that stopped a motorway in County Clare in 1999. Which tree?
Hint 1
It is in the list of documented facts, and it is named twice — once for the taboo and once for the motorway.
Hint 2
It has two common English names and an Irish one, and any of them will do.
Last hint
The first half of the word is a colour.
Give me the answer
The answer is The whitethorn. The whitethorn — hawthorn, sceach — which the tradition is specific about: cutting the thorn growing on a ring was reputed to be the death of whoever did it, and in 1999 a campaign led by the folklorist Eddie Lenihan saved one at Latoon from being felled for the M18. It is still there. The reason that is in a room on this site is the comparison it invites: a whole country will make an enormous, permanent, expensive accommodation on the strength of this matters and I am not going to justify it, and the same country will ask a Disabled person for a letter before it moves a desk.
Taking the answer is a real way through this, not a lesser one. Nothing is watching and nothing is written down.
