Ruby of Chissentra

The Ruby of Chissentra was a large magical scrying gem bestowed upon the traitor-priestess Shakti Hunzrin by Vhaeraun.

The gem was linked to a ruby bowl engraved with runes. In order to work, the gem had to be pressed against someone's forehead, causing searing pain and burning into their flesh. The gem would then work as a third eye for the wielder of the ruby bowl, who would be able not only to see through the gem, but also to mentally speak to the bearer and also to inflict excruciating psychic pain, which could reach lethal levels.

Liriel finally destroyed the stone during the confrontation between the drow and the Rashemi, where she casted a spell demanding a large gem as a material component. As a result of the spell, Brindlor, the latest bearer of the stone, had the stone removed from his forehead and bursted in an explosion of gore.

Bearers
Nisstyre was the first bearer of the ruby. When Shakti boasted the favour of Vhaeraun, she enlisted his help, searing the stone into his forehead in her plot to kill Liriel Baenre. He would wear it until his death in his magical duel against Liriel.

The last bearer of the stone would be Brindlor Zidorion, recruited by Gorlist in order to murder Liriel. He put the stone onto his forehead at Shakti's behest.
