Servants of Onyx

The Servants of Onyx are a faction of Vrakais who dominate the princedoms of the Aselaih Forest. They see Ork'luso as their true leader, despite him dying at the beginning of the Young World, and name their princedoms as mere princedoms because the true kingdom can only come about when Ork'luso returns from the dead.
The four highest princes and their followers all possess a different piece of Ork'luso's chrystallised remains, and even though they all share a goal in bringing Ork'luso back to life, the princes are in constant disagreement about whose princedom should be the heart of the kingdom. This disagreement has been ongoing for a very long time and has taken many forms, even causing war between the princedoms on several occasions.
Servants of Onyx have the ability to breathe and then capture onyxfire, which originates from Ork'luso's remains. Onyxfire is dark fire which is said to be able to sprout new life as easily as it can end life, and is almost exclusively wielded by the most powerful servants in the order. When the true kingdom is restored, the Servants of Onyx plan on ruling over their old enemies: the Alchemists of Ibrium--the ones who steal Chrystals from the Hrk'mun Chrystaldom and appropriate Alchemy which isn't truly theirs to begin with--and the Hredan Visaria--whose ancestors enslaved the Hrk'mun during the Relict Age.
