Beneath The Depths

Hello, my name is RogueHatter. My mage recently made it to the Beneath the Depths quest and got stuck. In the quest, it asks the player to retrieve the Faded map for Javier. I went through the Skull Cave until I reached the end room telling me to get one emerald block and "Flush it down underneath that raised thing." I have looked for a while and have no idea where I'm supposed to throw the emerald block. If you could tell me where I am supposed to throw the emerald block that would be greatly appreciated.

If you are in the room with the miniboss thing throw it on one of the graves

 

Thank you. Now this page isn't needed for me at least anymore.
