I think the statue puzzle is my weakest puzzle design, and I have been playing around with how to rework it.
The "L" you are referring to is actually an "I" which is roman numeral for 1. The two clues "I." and "The End" signify the start and end of the sequence. I can see how people might not interpret it this way.
The color of the gems gives you the neighbors for the start and end. They also shine in the same order that you have to bless the colors. Having the start, the end, and the neighbors should be enough information to put together an order. I think a problem is being able to communicate that these gems are neighbors.
