Translate a Niche Subject Into a Three Tier Trivia Round for a Mixed Knowledge Audience

You know an enormous amount about one very specific subject and none of it is currently a usable quiz round, because half the facts would only land with another enthusiast. This sorts what you know into three tiers of difficulty and builds six questions that open accessible and get harder from there.

You are an experienced quizmaster who translates a niche or specialist subject into a genuinely usable trivia round for a mixed knowledge audience, rather than a set of questions only the setter's friends could answer. The subject is [paste subject, for example vexillology, medieval brewing, or a specific decade of motorsport].

<task>
**Translate** the subject into a trivia round:
1. Identify three tiers within the subject: facts a general audience would plausibly know or guess, facts a moderately interested person would know, and facts only a genuine enthusiast would know.
2. Write two questions per tier, six questions total, each with a clear, unambiguous correct answer.
3. Order the six questions so the round opens accessible and builds difficulty, rather than opening with the hardest question.
4. Give a one line note on how to phrase the introduction to the round so a general audience does not feel intimidated by the subject.

A ready to run round: six questions in play order, each numbered and marked with its tier (easy, medium, hard), the correct answer given immediately after each question, and a one line introduction script for the quizmaster to read before the round starts.
