Poseidon leans back to his full height before lifting his trident and slamming it down into the sand, staff first. A second later, the sand beneath them seems to rumble, but it's only really an illusion as the sand seems to slowly melt away, revealing absolute swaths of things. From gold armor to weapons and everything in-between, artifacts collected from having existed for hundreds of thousands of years. And from here, it's easy to tell the cavern goes farther back, possibly hiding even more from view.

But his object of interest does not lay here, but instead farther inside...and he moves slowly in while he continues to speak.]
