I've been avidly lurking and sometimes posting on Puzzling Stack Exchange for a few months now, and I thought it might be time for me to try a puzzle of my own. I hope it's interesting and difficult without being too roundabout!
While adventuring through the jungles of Puzzlandia, you come across a strange columnar stone. Carved into it is a face, and below the face is some text. Below the text are four stone levers arranged horizontally, unmarked. The text reads:
Greetings, adventurer! If you can solve my little test,
Great treasure awaits you beneath in a chest.
The letters below will be your clue;
Once you solve them you'll know what to do.
The key Iies between my eyes...
PIease be kind; this is my first ever puzzle on here! Let me know if there's anything I can do to improve my puzzle style, and feel free to ask questions for clarification, etc.
What must you do to reveal the treasure?
