The Shade Isle Campaign
Eye of Izatu-Bal
A huge huge ruby about 8" across, flawless and faceted, the Eye of Izatu-Bal was discovered by the adventuring company in the possession of the Marsh-Gnomes. The object proved to be magical, but when Connor attempted to identify the ruby, his mind made contact with a mad, laughing spirit of purest Chaotic Evil that nearly overwhelmed his psyche entirely.
Later, after receiving a vision from the god Baldur warning them of the nature of the Eye and suggesting they destroy it, the party quickly determined that they had no means at the moment of permanently eliminating such a powerful and evil object. So, they decided to give it the same treatment as the Domstag Codex: they packed it inside a blessed chest filled with salt and silver and buried it away in some forgotten corner of the dwarven vaults underneath the palace at Dämmendell.
