The Tal Calar, sometimes referred to as "the Cullers", were an order created in the time of The Befores to wield and safeguard the Eari Stones. The name literally means "Sacred Eight" in High Vinthish.
Because the stones were created to trap magic, the guardians could not be spellcasters. One sect was originally going to be created from each of the eight races, which would be charged with continuing the work of hunting down magic uses, however, the elves refused to participate and allowed the humans to keep two eggs for themselves. The merfolk were also not given any stones, as they were not considered to be part of this conflict. The stone to represent them was also given to humans.
Currently, only two stones remain in possession, one by the Attawa, and one by the Vurg. How the Vurg came by the artifact remains a mystery. The rest have been lost to antiquity, all located on other continents.
Wraighs
In addition to keeping the stones, the Tal Calar are tasked with the caretaking of the creatures known as wraighs, which are used to sniff out magic. These creatures are not flesh and blood, but ethereal shadow. For this reason they are sometimes referred to as shade hounds. They are also not from the material plane, but they can be summoned here by the Tal Calar in order to carry out their task of finding and drawing magic from a wielder so that the Egg can absorb the energy.
Procedure
Whenever a sizeable enough amount of magical energy is released into the world, the wraighs can detect this. They literally smell it across the ethereal plane, and alert the Tal Calar keeper. The keeper becomes aware that a disturbance has been made because the ethereal shadow surface of the cauldron in which the wraighs are kept (which acts as a portal) begins to bubble and roil. The keeper then summons the wraighs to the material plane, where the wraighs then use a new portal, such as a starglass, to travel to the location of the disturbance. This allows the keeper to view the disturbance from their location. The wraighs can enter the starglass and form a connection to the location, similar to a wormhole through the ethereal plane, and they can exit on the other side using any reflective surface. Once there, they attack the source of the magical energy, goading it into releasing more magic, and once any amount of energy is released, the Eari stone can then latch onto it and draw it out from the source, trapping it within forever. The source, of course, dies in this process. Then the wraighs return to the cauldron where they are housed and the doorway is closed.
If a magic user were to die through any means, the magical energy within their material body would be released into the world, and this can also be detected. The wraighs can also lead the keeper to the location, where the Eari Stone would then proceed to soak up all the freshly released energy. This is the only time the stone does not need for the magic to be drawn out first.
Kobuka's Egg
The Attawa race is in possession of the last remaining Eari Stone in the known world (as the Vurg's home of Vir is considered beyond the known world). The others were lost to antiquity. The Attawa call it Kobuka's Egg, and it is protected by a guardian called the Dabimbula. They believe the Egg has unimaginable powers. Only the Dabimbula knows for sure what it is, and the secret is always passed down to the next.
