Four boxes are placed before you. Which would you try and open?
The small tortoiseshell box, embellished with gold, inside which some small creature seems to be squeaking.
The gleaming jet black box with a silver lock and key, marked with a mysterious rune that you know to be the mark of Merlin.
The ornate golden casket, standing on clawed feet, whose inscription warns that both secret knowledge and unbearable temptation lie within.
The small pewter box, unassuming and plain, with a scratched message upon it that reads ‘I open only for the worthy.’
