DISCLAIMER: This is a topic of conversation. Based solely of speculation. Feel free to leave your input! If you've finished Prison of Elders, you would take notice that there are 5 rounds. However, after completing the final round, you will gain access to the Treasure Room! To access the Treasure Room, you need to return to AirLock and drop down to the treasure room. Before reaching the treasure room, you will see that there are 4 or 5 empty rooms before arriving at the treasure room. I feel that there are hidden awards (similar to hidden chests in raids) within these empty rooms. There is just enough empty rooms for each round available! I don't know what variables are used to determine any treasure rewarded at the end. This is the point of this forum post, to create a conversation regarding possible hidden treasure! There can be different variables that can attend to this, such as finishing a round within a time frame, finishing a round flawlessly, etc! Comment with your ideas and opinions! Thanks for reading :)
