Cave of Stars (Raptured Falls)

''A cave we found on the surface, not far from Raptured Falls. What occurred that was odd to say the least, so I'm gonna detail any more such areas we find in an entry of their own."

History
''Who knows who created this cave. All that we know was that Adder sent us there on orders of Stygian who 'needed someone to explore the cave'. We (Luna, Dharyn, Phina, Marissa and I) went there and found... well, I'll list what happened below.

Appearance
''The Entrance to the Cave of Stars can be found above ground, near Raptured Falls. The Stygian Academy has been digging into the ground, and unearthed several cave systems. The Cave of Stars is the third cave on the right on the series of digups.''

After entering, follow the path down (avoiding the Blaststone and the Pinchhoppers until you encounter a stone door. Once you come upon a couple of stone doors (that Dharyn so nicely blasted off its hinges with his strength) you'll come across the stone room. That's the Cave of Stars. (Disclaimer, that's a name I came up with on my own, as mysterious caves don't exactly have plaques hanging upon their entrance.)

''Inside the room is a stone table with three stone seats around it. What would be the fourth has been broken off its hinges. Upon the table sits a rectangular piece with a slot in the middle. While at each of the inter-cardinal walls are four plaques, each one with a symbol inscribed upon it: fire, wind, water and earth, and a hole in the middle of it. Two heavily decayed and weathered banners sit upon the left and right side of the room, while the wall direct north (opposite that of the main door) sits completely empty. Yet, there is a reason why.''

The Puzzle
''The tablets were simple enough. The others, each one skilled in a unique element, went to the tablet that corresponded with their element. Upon using their elemental powers straight into the hole at the center of each one, four lights lit upon upon the table, feeding straight into the extrusion in the middle. Though it then took a while, Luna eventually figured out that the hole was a perfect fit for my sword. A sword I had gotten mere months ago... I... ...''

''A-anyway, after inserting my sword, the table parted and lifted the sword into the sky. A light shone through from the entrance, hitting the pommel of my sword and projecting a constellation upon the previously vacant north wall.''



The Reward
''The constellation wasn't our reward, as as the table parted, a stone plinth rose from the cavity in the ground. Upon a cushioned surface sat... what looked like a bone, though what it is I have no idea. To be honest, it looked... worthless. However, if someone went to this length to protect it, I can't assume that its as worthless as we think it is.''
