OK I already found it! But still pretty bugged the Pyramids cuz the teleport destination depends the Realm u actually are.

if i'm in Cyesal, i got teleported to the middle of the Sea (and get stucked)...if in Hiberhein...got stucked at the edge of the map...BUT...if in Silverglein...I got teleported right aside that chest...that was my clue...

Thanks for reply!
