Ebon Embrace

Necklace- A gold torc, inlaid with panels of ebony. While it has some powers, it's main function is to combine the three gems into a single item. There are three openings to hold the three gems; a slot in the center and two round holes on the sides. Crafted by Nulara Sephet of Mulhorand.
Obsidian Fang- A polished shard of volcanic obsidian five inches long, engraved with arcane symbols, from the Smoking Mountains in Unther. Enchanted by Horat the Skullmaster.
Star of Heaven- Star Sapphire, one inch in diameter, found by Phenir Shofan of Pyrados in Thay.
Eye of Rirgha- Ruby with a dark, central spindle shaped inclusion. Supposedly the eye of an ancient red dragon, it is not. It was pulled from a Yuan-ti temple statue and enchanted by Bareris of Chessenta.
