Dethrgal Crystals

"Dethrgal Tsu Rukar!" -The phrase that activates the crystals.

According to Legend these dark relics originate from a high-ranking demon of immense power and size named Dethrgal. It is said that many years ago he was slain in single combat against a valiant hero, but with his dying breath he cursed his foe, and the world of Golarion. Each drop of blood spilt from his mortal wound crystallized and were scattered to the winds.

Thusly, the threat of Dethrgal's power remains in Golarion long since his passing; for any person who wears the gem and utter the correct chant will be bestowed a fraction of the demon lord's strength.

The gems played a vital part in the machinations of Lord Kastagir, who sought to use them in conjunction with the local Thieves Guild to take over the town of Sandpoint. Fortunately however, his plans were thwarted by a trio of adventurers who had been roped into unwittingly smuggling gems into the town.

Looks
Reddish-orange gemstones that looks like crystallized fire. They are warm to the touch, and those of weak minds may feel great unease holding one without protection of any form.

Dethrgal crystals come in many sizes, but most commonly they are seen imbedded within arms, armor, jewelry or other items that one would wear. Thusly, they are more commonly found cut rather than uncut.

Abilities
The demonic power contained within the crystals can be transferred into the crystal's current wielder (provided they are in some manner "wearing" the crystal, and not just holding it) by uttering the phrase "Dethrgal Tsu Rukar".

The transformation that the phrase triggers is painful, and most mortals who have undergone it have perished horribly. The exact scope of the powers bestowed is unknown exactly because of how common fatality is during the transformation. After the phrase has been uttered and the power transferred the gem turns more dull in colour and it looses the magical property.

Notable Crystals and their users
Roderick's Gem: Used by Roderick The Fence to devastating effect. His size and constitution played part in how long he endured the transformation. Worn on a gauntlet.

Harbor Gathering: Many members of The Knaves were equipped with Dethrgal crystals at the Sandpoint harbor, awaiting a magical blessing by Kastagir that would give them the strength to survive the transformation. The Adventurers interfered however and activated the crystals early, resulting in the eventual deaths of the transforming thieves.

Rook's Gem: Held briefly by Rook but discarded and thrown away moments before it could activate. Rook was zapped by the gem just as he took it off, but no effect has shown itself yet. Worn on a womens choker.
