Camelot is a big place with a lot of problems, but there's one we care about. In this first paragraph, you must explain what that problem is. Our problem is that Camelot needs a leader.
Camelot needs a solution, and excalibur
is the (clever -- maybe even cheeky) name of the one thing that solves this one problem best. It sounds almost magical in how it could simply solve the problems above - problems that many people have tried to solve before. Now, you explain how it solves those problems: excalibur
tells you instantly whether or not a person is that leader.
In this final introductory paragraph, you explain how excalibur
works differently than most other attempted solutions. Specifically, it's hard to pull out of a stone, so only real leaders can do it.
