Many
The Hrakur are a Kinde of rock-based lifeforms which are found all over the Realmlands and the Voidsea. Found everywhere the Broadwave is found, it is widely speculated that they have some connection to it, though what it is is completely unknown.
Most are constructed by other Hrakur, but some are 'Born' - Random rocks in the Realmlands, the Voidsea, and occasionally on Void Islands or Coves. These 'Born' Hrakur usually become the leaders of various packs of Hrakur, while constructed Hrakur are their followers. Exceptions exist, but the criteria for these exceptions is not known to anyone other than the Hrakur themselves. The majority of Hrakur appear to form in the Realmlands, but Voidsea manifestations are far from unheard of.
Hrakur appear in every Sphere, and do not appear to be affiliated with any side in the Eternal War of Ideology. Though to most they seem unintelligent, they do appear to be responsive to outside stimulus, indicating that there is a degree of intelligence within them. they possess self-preservation, though have not explained who they are, or what they are doing to any Kinde. they are capable of communication, but seem to do so exclusively among themselves.
Only the most paranoid, totalitarian states actually do anything about the Hrakur - To most Spheres, their presence is a mystery, but so long as they do not disturb anyone, they are tolerated.
Connection to the Past
Historical researchers have pointed out that the Rune that many Hrakur have resembles the symbols many ancient Kin utilized before the Lost Age. The symbol appears to be a sort of power button, allowing the user to turn on or turn off a piece of technology. The symbol has fallen out of use in the Valhallan Age. Why this symbol appears on the Hrakur is unknown.
Within the Broadwave and Taekni broadly, the Rune can be used to provide wireless power to a piece of technology if required. Attempts to utilize this Rune against Hrakur have resulted in no effects to the Hrakur themselves. This suggests that they are alive in their own right, and not a type of automaton.
