Dragonborn's Hearth Honor
This tablet of Phyllite is covered by runes of a mysterius anchient language.
The runes of the stone change slowly. The Guardians of the Stone, a cabal of Dwarfish Invokers belive that they reveal words of power. The Ice Sculpters, a cabal of Elderian of the Winter court belive the stone is dangerous and a malevolent intellegence seeks to gain dominon over the dwarfish Invokers. Strangely enough, the Drow of the Barrier Peaks agree with the Elderian and seem to fear the stone as well.
