Randomly return 10 NPCs from an Obsidian vault using the Dataview plugin.

random-npcs.js

```dataviewjs
function randomElements(arr, n) {
  var result = new Array(n);
  var len = arr.length;
  if (n > len) throw new RangeError("randomElements: more elements taken than available");
  for (var i = len - 1; i >= len - n; i--) {
    var j = Math.floor(Math.random() * (i + 1));
    var temp = arr[i];
    result[len - i - 1] = arr[j];
    arr[i] = arr[j];
    arr[j] = temp;
  }
  return result;
}

dv.list(randomElements(dv.pages('"TTRPGs/Temporary White Circle"')
  .where(b => b.type == "NPC")
  .where(b => !b.deceased)
  .sort(b => b.file.link)
  .map(b => b.file.link),10)
  );
