I'm the one and only (the one of many) Jon.
There isn't much to me that you can't find out by browsing through my archive I guess.
Where my Percy Jackson fans at?
This necklace is a listing for all 5 beads in the series.
The Lightning Thief: shimmering sea-green trident surrounded by pitch black.
Sea of Monsters: a variation of Thalia’s pine with the golden fleece on its lowest branch.
Titan’s Curse: a crescent moon with shimmering stars.
Battle of the Labyrinth: a glowing blue delta surrounded by a labyrinth (the entire bead is decorated).
Last Olympian: The Empire State building with shimmering swirls around it (as described in the book).
Only the first and last bead are actually described in the books, the others are based off some dude imagination.
